Helmet Mounted Sight
A helmet-mounted display (HMD) is a headworn device that uses displays and optics to project imagery and/or symbology to the eyes. It provides visual information to the user where head protection is required – most notably in military aircraft. The display-optics assembly can be attached to a helmet or integrated into the design of the helmet. An HMD provides the pilot with situation awareness, an enhanced image of the scene, and in military applications cue weapons systems, to the direction their head is pointing. Applications which allow cuing of weapon systems are referred to as helmet-mounted sight and display (HMSD) or helmet-mounted sights (HMS). Requirement Aviation HMD designs serve these purposes: * using the head angle as a pointer to direct air-to-air and air-to-ground weapons seekers or other sensors (e.g., radar, FLIR) to a target by the pilot merely turning the helmet towards the target and operating a switch via HOTAS. In close combat, without HMDs, p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Military Helicopter
A military helicopter is a helicopter that is either specifically designed for or converted for usage by a military. A military helicopter's mission is a function of its design or conversion. The most common use of military helicopters is airlift, but transport helicopters can be modified or converted to perform other missions such as combat search and rescue (CSAR), medical evacuation (MEDEVAC), serving as an airborne command post, or even armed with weapons for close air support. Specialized military helicopters are intended to conduct specific missions. Examples of specialized military helicopters are attack helicopters, observation helicopters and anti-submarine warfare (ASW) helicopters. Types and roles Military helicopters play an integral part in the sea, land and air operations of modern militaries. Generally manufacturers will develop airframes in different weight/size classes which can be adapted to different roles through the installation of mission specific equipm ...

AIM-9 Sidewinder
The AIM-9 Sidewinder is a short-range air-to-air missile. Entering service with the United States Navy in 1956 and the Air Force in 1964, the AIM-9 is one of the oldest, cheapest, and most successful air-to-air missiles. Its latest variants remain standard equipment in most Western-aligned air forces. The Soviet K-13 (AA-2 "Atoll"), a reverse-engineered copy of the AIM-9B, was also widely adopted. Low-level development started in the late 1940s, emerging in the early 1950s as a guidance system for the modular Zuni rocket. This modularity allowed for the introduction of newer seekers and rocket motors, including the AIM-9C variant, which used semi-active radar homing and served as the basis of the AGM-122 Sidearm anti-radar missile. Due to the Sidewinder's infrared guidance system, the brevity code " Fox two" is used when firing the AIM-9. Originally a tail-chasing system, early models saw extensive use during the Vietnam War, but had a low success rate (8% hit rate with th ...

F-4 Phantoms
The McDonnell Douglas F-4 Phantom II is an American Tandem#Aviation, tandem two-seat, twinjet, twin-engine, all-weather, long-range supersonic aircraft, supersonic jet interceptor aircraft, interceptor and fighter-bomber that was developed by McDonnell Aircraft for the United States Navy.Swanborough and Bowers 1976, p. 301. It entered service with the Navy in 1961, then was adopted by the United States Marine Corps, and the United States Air Force, and within a few years became a major part of their air arms. A total of 5,195 Phantoms were built from 1958 to 1981, making it the List of most produced aircraft, most-produced American supersonic military aircraft in history and a signature combat aircraft of the Cold War."F-4 Phantoms Phabulous 40th" Boeing.

F-15
The McDonnell Douglas F-15 Eagle is an American twin-engine, all-weather fighter aircraft designed by McDonnell Douglas (now part of Boeing). Following reviews of proposals, the United States Air Force (USAF) selected McDonnell Douglas's design in 1969 to meet the service's need for a dedicated air superiority fighter. The Eagle took its maiden flight in July 1972, and entered service in 1976. It is among the most successful modern fighters, with over 100 victories and no losses in aerial combat, with the majority of the kills by the Israeli Air Force.Spick 2000, p. 127. The Eagle has been exported to many countries, including Israel, Japan, and Saudi Arabia. Although the F-15 was originally envisioned as a pure air superiority fighter, its design included a secondary ground-attack capability that was largely unused. It proved flexible enough that an improved all-weather strike derivative, the F-15E Strike Eagle, was later developed, entered service in 1989 and has been exp ...

F-14
The Grumman F-14 Tomcat is an American carrier-capable supersonic aircraft, supersonic, twinjet, twin-engine, Tandem#Aviation, tandem two-seat, twin-tail, all-weather-capable variable-sweep wing fighter aircraft. The Tomcat was developed for the United States Navy's Naval Fighter Experimental (VFX) program after the collapse of the General Dynamics–Grumman F-111B, General Dynamics-Grumman F-111B project. A large and well-equipped fighter, the F-14 was the first of the American Teen Series fighters, which were designed incorporating aerial warfare, air combat experience against smaller, more maneuverable List of Mikoyan and MiG aircraft, MiG fighters during the Vietnam War. The F-14 first flew on 21 December 1970 and made its first deployment in 1974 with the U.S. Navy aboard the aircraft carrier , replacing the McDonnell Douglas F-4 Phantom II. The F-14 served as the U.S. Navy's primary maritime air superiority fighter, fleet defense interceptor aircraft, interceptor, and tac ...

ACEVAL/AIMVAL
The Air Combat Evaluation (ACEVAL) and the Air Intercept Missile Evaluation (AIMVAL) were two back-to-back Joint Test & Evaluations chartered by the United States Department of Defense that ran from 1974-78 at Nellis Air Force Base in Nevada. Both the U.S. Air Force and U.S. Navy participated, contributing a team of F-15 Eagle and F-14 Tomcat fighter aircraft and using the local F-5E Aggressor aircraft as the Red Force. The fundamental question that needed to be answered was one of "quantity vs quality". Mock engagements showed that cheaper, lower-technology fighters armed with all-aspect missiles were able to destroy the more advanced, expensive F-15s and F-14s. These results of the AIMVAL/ACEVAL testing led to the Air Force decision to structure its fighter forces with a balance of cheaper F-16s along with the more expensive F-15s, and the Navy took a similar strategy in procuring cheaper F/A-18s along with the more expensive F-14s. The results had other impacts as well, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Infrared Homing
Infrared homing is a Missile guidance#Passive homing, passive weapon guidance system which uses the infrared (IR) light emission from a target to track and follow it seamlessly. Missiles which use infrared seeking are often referred to as "heat-seekers" since infrared is radiated strongly by hot bodies. Many objects such as people, vehicle engines and aircraft generate and emit heat and so are especially visible in the infrared wavelengths of light compared to objects in the background. Infrared seekers are passive devices, which, unlike radar, provide no indication that they are tracking a target. That makes them suitable for sneak attacks during visual encounters or over longer ranges when they are used with a forward looking infrared or similar cueing system. Heat-seekers are extremely effective: 90% of all timeline of United States military operations, United States air combat losses between 1984 and 2009 were caused by infrared-homing missiles. They are, however, subject ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Popular Electronics
''Popular Electronics'' was an American magazine published by John August Media, LLC, and hosted at TechnicaCuriosa.com. The magazine was started by Ziff-Davis Publishing Company in October 1954 for electronics hobbyists and experimenters. It soon became the "World's Largest-Selling Electronics Magazine". In April 1957, Ziff-Davis reported an average net paid circulation of 240,151 copies. ''Popular Electronics'' was published until October 1982 when, in November 1982, Ziff-Davis launched a successor magazine, ''Computers & Electronics''. During its last year of publication by Ziff-Davis, ''Popular Electronics'' reported an average monthly circulation of 409,344 copies.
