RU-38
The Schweizer RU-38 Twin Condor is a two or three-seat, fixed gear, low wing, twin boom covert reconnaissance aircraft. RU-38 is the US military designation for the aircraft, indicating ''Utility, Reconnaissance''. The Schweizer company model number is Schweizer SA 2-38A Condor and, in its three-seat configuration, Schweizer SA 3-38A Condor Based on the Schweizer SGM 2-37 motor glider, a total of five RU-38s were produced between 1995 and 2005. The aircraft remains in production by Sikorsky Aircraft after acquiring Schweizer. Background The development of the Schweizer SGM 2-37 motor glider for training use at the United States Air Force Academy led to two reconnaissance versions of that design, carrying the company model numbers SA 2-37A and SA 2-37B. In Central Intelligence Agency, US Army and US Coast Guard service these were designated RG-8A and B. The RG-8s were employed in border security and surveillance missions. In the mid-1990s the Coast Guard decided that the air ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Schweizer Aircraft Corporation
The Schweizer Aircraft Corporation was an American manufacturer of sailplanes, agricultural aircraft and helicopters located in Horseheads, New York. It was incorporated in 1939 by three Schweizer brothers (Paul, William, and Ernest), who built their first glider, the SGP 1-1, in 1930. Previously the oldest privately owned aircraft company in the United States, Schweizer was acquired by Sikorsky Aircraft Corporation of Stratford, Connecticut in 2004, and became a diversified aerospace company. Schweizer Aircraft ceased operations in 2012. It was sold to Schweizer R.S.G. in 2018 and production lines were opened again in Fort Worth, Texas. The company was producing three helicopter models in 2021. History The company grew out of the Mercury Glider Club which produced the first two Schweizer gliders in the Schweizers' barn. The company was originally called the Schweizer Metal Aircraft Company. Attorney Bob McDowell indicated to the Schweizers that they should move their manu ...

Schweizer SGM 2-37
The Schweizer SGM 2-37 is a two-place, side-by-side, fixed gear, low wing motor glider.Said, Bob: ''1983 Sailplane Directory, Soaring Magazine'', page 131. Soaring Society of America, November 1983. USPS 499–920 A total of twelve were produced between 1982 and 1988, including nine for the United States Air Force Academy, which designated it the TG-7A. The TG-7A was retired from USAFA service in April 2003. The basic airframe was later developed into the SA 2-37A and B covert surveillance aircraft. Development Schweizer had flown a Schweizer SGU 1-19 as a motor glider in 1946 without putting the design into production. In 1958 the company carried out a design study of a powered aircraft using the wings and tail of the 1-26 designated as the Schweizer SA 1-30, but after some test flying and modification it was not put into production. A two-seat version of the 1-30, the Schweizer SA 2-31 was completed in 1960 but not put into production due to competition in the light aircraf ...

Continental IO-550
The Continental IO-550 engine is a large family of 9 liter fuel injected six-cylinder, horizontally opposed, air-cooled aircraft engines that were developed for use in light aircraft by Teledyne Continental Motors. The first IO-550 was delivered in 1983 and the type remains in production. The IOF-550 is an Aerosance FADEC equipped version of the same basic engine, the TSIO-550 is a dual turbocharged version and the TSIOL-550 is a liquid-cooled variant. There is no O-550 engine, which would be a carburetor-equipped variant, hence the base model is the IO-550. This engine family competes with the Lycoming IO-580 series which are also six-cylinder engines with similar power output and weight. Design and development The IO-550 family of engines was developed from the IO-520 series, with the stroke increased from 4.00 to 4.25 inches, increasing the displacement to 552 in³ (9.05 L). The engine family covers a power range from to . The engines were first developed in the early ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Twin Boom
A twin-boom aircraft is characterised by two longitudinal booms (extended nacelle-like bodies). The booms may contain ancillary items such as fuel tanks and/or provide a supporting structure for other items. Typically, twin tailbooms support the tail surfaces, although on some types such as the Rutan Model 72 Grizzly the booms run forward of the wing. The twin-boom configuration is distinct from twin-fuselage designs in that it retains a central fuselage. Design The twin-boom configuration is distinct from the twin fuselage type in having a separate, short fuselage housing the pilot and payload. It has been adopted to resolve various design problems with the conventional empennage for aircraft in different roles. Engine mounting For a single engine with a propeller in the pusher configuration or a jet engine, a conventional tail requires the propeller or exhaust to be moved far aft, requiring either a very long driveshaft or jet pipe and thus reducing propulsive efficien ...

High Frequency
High frequency (HF) is the ITU designation for the range of radio frequency electromagnetic waves (radio waves) between 3 and 30 megahertz (MHz). It is also known as the decameter band or decameter wave as its wavelengths range from one to ten decameters (ten to one hundred meters). Frequencies immediately below HF are denoted medium frequency (MF), while the next band of higher frequencies is known as the very high frequency (VHF) band. The HF band is a major part of the shortwave band of frequencies, so communication at these frequencies is often called shortwave radio. Because radio waves in this band can be reflected back to Earth by the ionosphere layer in the atmosphere – a method known as "skip" or " skywave" propagation – these frequencies are suitable for long-distance communication across intercontinental distances and for mountainous terrains which prevent line-of-sight communications. The band is used by international shortwave broadcasting stations ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Very High Frequency
Very high frequency (VHF) is the ITU designation for the range of radio frequency electromagnetic waves ( radio waves) from 30 to 300 megahertz (MHz), with corresponding wavelengths of ten meters to one meter. Frequencies immediately below VHF are denoted high frequency (HF), and the next higher frequencies are known as ultra high frequency (UHF). VHF radio waves propagate mainly by line-of-sight, so they are blocked by hills and mountains, although due to refraction they can travel somewhat beyond the visual horizon out to about 160 km (100 miles). Common uses for radio waves in the VHF band are Digital Audio Broadcasting (DAB) and FM radio broadcasting, television broadcasting, two-way land mobile radio systems (emergency, business, private use and military), long range data communication up to several tens of kilometers with radio modems, amateur radio, and marine communications. Air traffic control communications and air navigation systems (e.g. VOR and ILS) wo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ultra High Frequency
Ultra high frequency (UHF) is the ITU designation for radio frequency, radio frequencies in the range between 300 megahertz (MHz) and 3 gigahertz (GHz), also known as the decimetre band as the wavelengths range from one meter to one tenth of a meter (one decimeter). Radio waves with frequencies above the UHF band fall into the super-high frequency (SHF) or microwave frequency range. Lower frequency signals fall into the VHF (very high frequency) or lower bands. UHF radio waves propagate mainly by Line-of-sight propagation, line of sight; they are blocked by hills and large buildings although the transmission through building walls is strong enough for indoor reception. They are used for UHF television broadcasting, television broadcasting, cell phones, satellite communication including GPS, personal radio services including Wi-Fi and Bluetooth, walkie-talkies, cordless phones, satellite phones, and numerous other applications.

Night Vision Goggles
A night-vision device (NVD), also known as a night optical/observation device (NOD), night-vision goggle (NVG), is an optoelectronic device that allows visualization of images in low levels of light, improving the user's night vision. The device enhances ambient visible light and converts near-infrared light into visible light which can be seen by the user; this is known as I2 ( image intensification). By comparison, viewing of infrared thermal radiation is referred to as thermal imaging and operates in a different section of the infrared spectrum. A night vision device usually consists of an image intensifier tube, a protective housing, and may have some type of mounting system. Many NVDs also include a protective sacrificial lens, mounted over the front lens (ie. objective lens) on NVDs to protect the latter from damage by environmental hazards and some can incorporate [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Edwards Air Force Base
Edwards Air Force Base (AFB) is a United States Air Force installation in California. Most of the base sits in Kern County, but its eastern end is in San Bernardino County and a southern arm is in Los Angeles County. The hub of the base is Edwards, California. The base was named after World War II USAAF veteran and test pilot Capt. Glen Edwards in 1950; prior to then the facility was named Muroc Air Force Base.

445th Flight Test Squadron
The 445th Test Squadron is a United States Air Force squadron (aviation), squadron. It is assigned to the 412th Operations Group at Edwards Air Force Base, California. The 445th is part of the Air Force Test Center. History World War II The squadron (aviation), squadron's first predecessor was activated at Orlando Army Air Base, Florida as the 445th Fighter Squadron in early 1943 as part of the Army Air Force School of Applied Tactics (AAFSAT). AAFSAT's function was to train cadre (military), cadres from newly formed units in combat operations under simulated field conditions as the cores around which new combat groups would be formed. The 445th trained pilots and furnished cadres to night fighter units. Later, it engaged in mock combat missions over the AAFSAT range training pilots in combat maneuvers, flying a wide variety of fighters and bombers. It remained at the AAFSAT until March 1944 when the training mission of the groups was replaced by the 903d Army Air Forces Ba ...

Forward Looking Infrared
Forward-looking infrared (FLIR) cameras, typically used on military and civilian aircraft, use a thermographic camera that senses infrared radiation. The sensors installed in forward-looking infrared cameras, as well as those of other thermal imaging cameras, use detection of infrared radiation, typically emitted from a heat source (thermal radiation), to create an image assembled for video output. They can be used to help pilots and drivers steer their vehicles at night and in fog, or to detect warm objects against a cooler background. The wavelength of infrared that thermal imaging cameras detect is 3 to 12 μm and differs significantly from that of night vision, which operates in the visible light and near-infrared ranges (0.4 to 1.0 μm). Design Infrared light falls into two basic ranges: ''long-wave'' and ''medium-wave''. Long-wave infrared (LWIR) cameras, sometimes called "far-infrared", operate at 8 to 12 μm and can see heat sources, such as hot en ...
