Lee Morgan - The Sidewinder

The Mk36 solid-propellant rocket motor provides propulsion for the missile. A reduced-smoke propellant makes it difficult for a target to see and avoid the missile.

This section also features the launch lugs used to hold the missile to the rail of the missile launcher.

The forward of the three lugs has two contact buttons that electrically activate the motor igniter. The fins provide stability from an aerodynamic point of view, but it is the " rollerons " at the end of the wings providing gyroscopic precession to free-hinging control surfaces in the tail that prevent the missile from spinning in flight.

The wings and fins of the AIM-9X are much smaller and control surfaces are reversed from earlier Sidewinders with the control section located in the rear, while the wings up front provide stability.

The AIM-9X also features vectored thrust or jet vane control to increase maneuverability and accuracy, with four vanes inside the exhaust that move as the fins move.

The last upgrade to the missile motor on the AIM-9X is the addition of a wire harness that allows communication between the guidance section and the control section, as well as a new bus to connect the guidance section with the launcher's digital umbilical.

The detector was mounted in front of the mirror. When the long axis of the mirror, the missile axis and the line of sight to the target all fell in the same plane, the reflected rays from the target reached the detector provided the target was not very far off axis.

Therefore, the angle of the mirror at the instant of detection w1 estimated the direction of the target in the roll axis of the missile.

If the target was further off axis, the rays reaching the detector would be reflected from the outer edge of the mirror.

If the target was closer on axis, the rays would be reflected from closer to the centre of the mirror. Rotating on a fixed shaft, the mirror's linear speed was higher at the outer edge.

Therefore, if a target was further off-axis, its "flash" in the detector occurred for a briefer time, or longer if it was closer to the center.

The off-axis angle could then be estimated by the duration of the reflected pulse of infrared. The Sidewinder also included a dramatically improved guidance algorithm.

The Enzian attempted to fly directly at its target, feeding the direction of the telescope into the control system as it if were a joystick.

This meant the missile always flew directly at its target, and under most conditions would end up behind it, "chasing" it down. This meant that the missile had to have enough of a speed advantage over its target that it did not run out of fuel during the interception.

The Sidewinder is not guided on the actual position recorded by the detector, but on the change in position since the last sighting.

So if the target remained at 5 degrees left between two rotations of the mirror, the electronics would not output any signal to the control system.

Consider a missile fired at right angles to its target; if the missile is flying at the same speed as the target, it should "lead" it by 45 degrees, flying to an impact point far in front of where the target was when it was fired.

If the missile is traveling four times the speed of the target, it should follow an angle about 11 degrees in front.

In either case, the missile should keep that angle all the way to interception, which means that the angle that the target makes against the detector is constant.

It was this constant angle that the Sidewinder attempted to maintain. This " proportional pursuit " system is very easy to implement, yet it offers high-performance lead calculation almost for free and can respond to changes in the target's flight path, [8] which is much more efficient and makes the missile "lead" the target.

However, this system also requires the missile to have a fixed roll-axis orientation. If the missile spins at all, the timing based on the speed of rotation of the mirror is no longer accurate.

Correcting for this spin would normally require some sort of sensor to tell which way is "down" and then adding controls to correct it.

Instead, small control surfaces were placed at the rear of the missile with spinning disks on their outer surface; these are known as rollerons.

Airflow over the disk spins them to a high speed. If the missile starts to roll, the gyroscopic force of the disk drives the control surface into the airflow, cancelling the motion.

Thus the Sidewinder team replaced a potentially complex control system with a simple mechanical solution. During World War II , various researchers in Germany designed infrared guidance systems of various complexity.

Hamburg used a single IR photocell as its detector along with a spinning disk with lines painted on it, alternately known as a "reticle" or "chopper".

The reticle spun at a fixed speed, causing the output of the photocell to be interrupted in a pattern, and the details of this pattern indicated the bearing of the target.

Although Hamburg and similar devices like Madrid were essentially complete, the work of mating them to a missile had not been carried out by the time the war ended.

In the immediate post-war era, Allied military intelligence teams collected this information, along with many of the engineers working on these projects.

Several lengthy reports on the various systems were produced and disseminated among the western aircraft firms, while a number of the engineers joined these companies to work on various missile projects.

By the late s a wide variety of missile projects were underway, from huge systems like the Bell Bomi [ clarification needed ] to small systems like air-to-air missiles.

McLean initially called his effort "Local Fuze Project " using laboratory funding, volunteer help and fuze funding to develop what it called a heat-homing rocket.

It subsequently received designation as a program in The name Sidewinder was selected in and is the common name of Crotalus cerastes , a venomous rattlesnake , which uses infrared sensory organs to hunt warm-blooded prey.

Originally called the Sidewinder 1 , the first live firing was on 3 September Marine Corps to modify their Sabres to carry the Sidewinder.

In the first encounter on 24 September , the Sidewinders were used to ambush the MiGs as they flew past the Sabres thinking they were invulnerable to attack.

The MiGs broke formation and descended to the altitude of the Sabres in swirling dogfights. This action marked the first successful use of air-to-air missiles in combat, the downed MiGs being their first casualties.

Soviet engineers later said that the captured Sidewinder served as a "university course" in missile design and substantially improved Soviet air-to-air capabilities.

There may have been a second source for the copied design: according to Ron Westrum in his book Sidewinder , [14] the Soviets obtained the plans for Sidewinder from a Swedish Air Force Colonel, Stig Wennerström.

According to Westrum, Soviet engineers copied the AIM-9 so closely that even the part numbers were duplicated, although this has not been confirmed from Soviet sources.

The Sidewinder subsequently evolved through a series of upgraded versions with newer, more sensitive seekers with various types of cooling and various propulsion, fuze , and warhead improvements.

Although each of those versions had various seeker, cooling, and fusing differences, all but one shared infrared homing. The exception was the U.

Only about 1, of these weapons were produced, many of which were later rebuilt as the AGM Sidearm anti-radiation missile. Performance of the Sidewinders launched [15] during the war was not as satisfactory as hoped.

The USAF conducted the classified Red Baron Report while the Navy conducted a study concentrating primarily on performance of air-to-air weapons that was informally known as the " Ault Report ".

The impact of both studies resulted in modifications to the Sidewinder by both services to improve its performance and reliability in the demanding air-to-air arena.

The Navy Sidewinder design progression went from the early production B model to the D model that was used extensively in Vietnam. The G and H models followed with new forward canard design improving ACM performance and expanded acquisition modes and improved envelopes.

The "Hotel" model followed shortly after the "Golf" and featured a solid state design that improved reliability in the carrier environment where shock from catapult launches and arrested landings had a deteriorating effect on the earlier vacuum tube designs.

The Ault report had a strong impact on Sidewinder design, manufacture, and handling. The "Echo" was an improved version of the basic AIM-9B featuring larger forward canards as well as a more aerodynamic IR seeker and an improved rocket motor.

The missile, however still had to be fired at the rear quarter of the target, a drawback of all early IR missiles. The Juliet model could be launched at up to 7.

The AIM-9J was widely exported. In total Sidewinders were fired during the Vietnam War, resulting in a kill probability of 0. Its first use in a large-scale conflict was by the United Kingdom during the Falklands War.

In combat uses of the AIM-9L, opponents had not developed tactics for the evasion of head-on missile shots with it, making them more vulnerable.

The "Lima" was distinguished from earlier Sidewinder variants by its double delta forward canard configuration and natural metal finish of the guidance and control section.

There are a number of "Lima" variants in operational service at present. First developed was the 9L Tactical, which is an upgraded version of the basic 9L missile.

The subsequent AIM-9M "Mike" has the all-aspect capability of the L model while providing all-around higher performance.

The M model has improved capability against infrared countermeasures , enhanced background discrimination capability, and a reduced-smoke rocket motor.

These modifications increase its ability to locate and lock-on to a target and decrease the chance of missile detection.

Deliveries of the initial AIM-9M-1 began in The AIM-9X concept is to use reprogrammable software to permit upgrades without disassembly.

The Navy began development of AIM-9R, a Sidewinder seeker upgrade in that featured a focal-plane array FPA seeker using video-camera type charge-coupled device CCD detectors and featuring increased off-boresight capability.

The technology at the time was restricted to visual daylight use only and the USAF did not agree on this requirement, preferring another technology path.

AIM-9R reached flight test stage before it was cancelled and subsequently both services agreed to a joint development of the AIM-9X variant.

China Lake developed an improved compressed carriage control configuration titled BOA. The BOA design reduced size of control surfaces, eliminating the rollerons, and returned to simple forward-canard design.

Meanwhile, the Air Force was pursuing a parallel effort to develop a compressed carriage version of Sidewinder, called Boxoffice, for the F Congress eventually insisted the services work on a joint effort resulting in the AIM-9M, thereby compromising without exploring the improved off boresight and kinematic capability potential offered by Agile.

At that point, the Soviet Union took the lead in SRM technology and correspondingly fielded improved infrared countermeasures IRCM to defeat or reduce the effectiveness of the latest Sidewinders.

The first draft of the requirement was ready by and the primary competitors were Raytheon and Hughes.

Joint Helmet Mounted Cueing System , and a totally new three-dimensional thrust-vectoring control TVC system providing increased turn capability over traditional control surfaces.

Though not part of the original requirement, AIM-9X demonstrated potential for a Lock-on After Launch capability, allowing for possible internal use for the F , F Raptor and even in a submarine-launched configuration for use against ASW platforms.

Objectives of the operational test were due to be completed by the third quarter of In February , the U. The USN projected that the new missile would have a 60 percent longer range, modern components to replace old ones, and an insensitive munitions warhead, which is more stable and less likely to detonate by accident, making it safer for ground crews.

Modifying the AIM-9X was seen as a cost-effective alternative to developing a new missile in a time of declining budgets.

To achieve the range increase, the rocket motor would have a combination of increased performance and missile power management.

A version for the U. In this configuration an operator sat in a protected capsule that was incorporated into the launcher assembly that rotated as an integrated unit.

The Chaparral was introduced into service in and remained an integral part of the Army's air defense network until The Sidewinder was also the basis for the AGMA Sidearm anti-radiation missile utilizing an AIM-9C guidance section modified to detect and track a radiating ground-based air defense system radar.

The target-detecting device is modified for air-to-surface use, employing forward hemisphere acquisition capability.

Sidearm stocks have apparently been expended, and the weapon is no longer in the active inventory. China Lake experimented with Sidewinders in the air-to-ground mode including use as an anti-tank weapon.

Starting from , the AIM-9X demonstrated its ability as a successful light air-to-ground missile.

This project developed to use by attack helicopters and ground launchers. Under the High Altitude Project, engineers at China Lake mated a Sidewinder warhead and seeker to a Sparrow rocket motor to experiment with usefulness of a larger motor.

Within a few minutes of being born, the baby sidewinder escapes from a thin, transparent membrane.

The young stay at their natal burrow for seven to ten days until they shed, [12] and then they disappear and have no future contact with their mother or their litter mates.

While the density of sidewinders can be up to one individual per hectare , they rarely encounter each other except during mating season.

Sidewinders have an extraordinarily accelerated lifecycle, with natural life expectancies of females of about five years.

Sidewinders can live more than 20 years when well fed in captivity even females. Thus, energetics apparently factor heavily into natural female mortality, [13] whereas predation might be the primary pressure on males.

In the wild, females often die of exhaustion after giving birth, but the lives of sidewinders are also cut short by predation, diseases, and vehicle encounters.

These snakes are venomous, but possess a weaker venom than many other rattlesnakes. This, together with the smaller size of their venom glands, makes them less dangerous than their larger relatives.

Still, any rattlesnake bite can be fatal and should be taken seriously and medical attention sought immediately. Envenomation can cause pain, swelling, hemorrhagic bleb formation and ecchymosis i.

Swelling, while not particularly severe, occasionally may involve entire limbs and the trunk.

Envenomation's systemic symptoms include nausea, dizziness, chills, coagulopathy blood disorders and shock.

Although the bite was described as no more painful than a pin prick, a doctor was seen within about 25 minutes, and 10 cc of antivenin were administered.

Within 2. Ovine-derived antivenom, CroFab, for North American pit viper envenomation has been widely available since Consultation with a local expert or regional poison control center should be obtained before administering antivenom.

The sidewinder Crotalus cerastes , also known as the horned rattlesnake and sidewinder rattlesnake , [3] is a venomous pit viper species belonging to the genus Crotalus rattlesnakes and is found in the desert regions of the southwestern United States and northwestern Mexico.

Three subspecies are currently recognized, including the nominate subspecies described here. Usually, 21 rows of keeled dorsal scales occur midbody.

This adaptation may help shade the eyes or prevent sand drifting over them as the snake lies almost buried in it.

The color pattern consists of a ground color that may be cream, buff, yellowish-brown, pink, or ash gray, overlaid with dorsal blotches subrhombic or subelliptical in shape.

Klauber and Neill describe the ability of this species to display different coloration depending on the temperature—a process known as metachrosis.

Sidewinder, horned rattlesnake, sidewinder rattlesnake, Mojave Desert sidewinder for C. In the southwestern United States, this species is found in the desert region of south eastern California , southern Nevada , southwestern Utah , and western Arizona.

In northwestern Mexico, it is found in western Sonora and eastern Baja California. The population trend was stable when assessed in The common name sidewinder alludes to its unusual form of locomotion, which is thought to give it traction on windblown desert sand, but this peculiar locomotor specialization is used on any substrate over which the sidewinder can move rapidly.

As its body progresses over loose sand, it forms a letter J-shaped impression, with the tip of the hook pointing in the direction of travel.

Sidewinding is also the primary mode of locomotion in other desert sand dwellers, such as the horned adder Bitis caudalis and Peringuey's adder Bitis peringueyi , but many other snakes can assume this form of locomotion when on slick substrates e.

Sidewinder rattlesnakes can use sidewinding to ascend sandy slopes by increasing the portion of the body in contact with the sand to match the reduced yielding force of the inclined sand, allowing them to ascend up to the maximum possible sand slope without slip.

The species is nocturnal during hot months and diurnal during the cooler months of its activity period, which is roughly from November to March probably longer in the southern part of its range.

Juveniles use their tails to attract lizard prey, a behavior termed " caudal luring ". Adults lose this behavior as they make the transition from lizard prey to their primary diet of desert rodents.

Sidewinder juveniles appear to mimic both life stages of lepidopterans in their luring motions. Their fast luring motions resemble the fluttering of a moth, and their slower tail movements resemble a caterpillar.

Both movements have been observed to attract prey lizards. Neonatal sidewinders engage in a remarkable behavioral homeothermy that has not been observed in any other type of snake.

Most often, gravid females select an east-facing, small-diameter rodent burrow for giving birth. The dynamic mass of neonates modifies the thermal environment at the burrow entrance such that the young can occupy a location that would ordinarily become lethally hot for an individual neonate or even an adult.

Females produce up to 18 young, with an average of about 10 per litter. Like most other viperids , the young are born enveloped in thin embryonic membranes, from which they emerge shortly after being expelled from the mother.

The young stay with their mother in a burrow for seven to 10 days, shed for the first time, then leave their natal burrow. During this time, the mother is thought to guard and protect them from predators.

Sidewinders mature at two to three years of age, are capable of reproducing annually, and give birth to live young.

Some females skip reproductive opportunities. Sidewinders mate in April through May and sometimes in fall. When the male and female mate, the male snake crawls along the female's back, rubbing her with his chin to stimulate or arouse her.

The male then will wrap his tail around her tail, and then will try to bring their cloacae together. The cloaca is the posterior body opening through which snakes both excrete waste and reproduce.

If the female wants to mate, she will lift her tail and allow him to mate with her. The snakes can mate for several hours, and if one of the snakes decides to move, the other is dragged along.

Females might mate with several males in a season. Females give birth to five to 18 young in late summer to early fall.

The young are born six to eight inches long. The birth takes only two to three hours altogether. Within a few minutes of being born, the baby sidewinder escapes from a thin, transparent membrane.

The young stay at their natal burrow for seven to ten days until they shed, [12] and then they disappear and have no future contact with their mother or their litter mates.

While the density of sidewinders can be up to one individual per hectare , they rarely encounter each other except during mating season.
