Hiller Helicopters
Hiller Aircraft Corporation is an American private aerospace company, based in Firebaugh, California. It was founded in 1942 as Hiller Industries by Stanley Hiller to develop helicopters. History Stanley Hiller, then seventeen, established the first helicopter factory on the West Coast of the United States, located in Berkeley, California, in 1942, under the name "Hiller Industries," to develop his design for the Coaxial-rotor aircraft, coaxial-rotor Hiller XH-44, XH-44 "Hiller-Copter" for the U.S. Army. The XH-44 became operational in 1944.Hiller Helicoptertimeline(accessed Nov 9 2011) In collaboration with Henry J. Kaiser, it became United Helicopters in 1945. In the postwar years, United Helicopter produced a number of innovative helicopter designs for military and civilian purposes, including coaxial-rotor and tailless designs, as well as more conventional models. In January, 1949, a Hiller OH-23 Raven, Hiller 360 became the first civilian helicopter to cross the United ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aerospace
Aerospace is a term used to collectively refer to the atmosphere and outer space. Aerospace activity is very diverse, with a multitude of commercial, industrial, and military applications. Aerospace engineering consists of aeronautics and astronautics. Aerospace organizations research, design, manufacture, operate, maintain, and repair both aircraft and spacecraft. The border between space and the atmosphere has been proposed as above the ground according to the physical explanation that the air density is too low for a lifting body to generate meaningful lift force without exceeding orbital velocity. This border has been called the Kármán line. Overview In most industrial countries, the aerospace industry is a co-operation of the public and private sectors. For example, several states have a civilian space program funded by the government, such as NASA, National Aeronautics and Space Administration in the United States, European Space Agency in Europe, the Canadian Space A ...

Hiller VZ-1 Pawnee
The Hiller VZ-1 Pawnee (U.S. Army designation; earlier Army designation: HO-1) is a unique direct-lift rotor aircraft, using contra-rotating ducted fans for lift inside a flying platform upon which the single pilot shifted body weight for directional control. The platform was developed starting in 1953 under an Office of Naval Research (ONR) contract to Hiller Aircraft, and flew successfully beginning in 1955. Design and development The original concept had been developed by Charles H. Zimmerman in the late 1940s. Further development followed, both by Hiller Aircraft and the De Lackner Company. There were two main models, the ONR model 1031-A-1, and the somewhat larger VZ-1 Pawnee model produced in 1956 for the U.S. Army. Three of each model were built as prototypes. Neither of the variants was put into production. The smaller ONR model used two Nelson H-59 piston engines, coupled to the propellers by a modified helicopter transmission built by the Industrial Power Divisio ...

Tip Jet
A tip jet is a jet nozzle at the tip of some helicopter rotor blades, used to spin the rotor, much like a Catherine wheel firework. Tip jets replace the normal shaft drive and have the advantage of placing no torque on the airframe, thus not requiring the presence of a tail rotor. Some simple monocopters are composed of nothing but a single blade with a tip rocket. Tip jets can use compressed air, provided by a separate engine, to create jet thrust. Other types use a system that functions similarly to the afterburner (reheat) on a conventional jet engine, except that instead of reheating a gas jet, they serve as the primary heater, creating greater thrust than the flow of pre-compressed air alone; the best description of this is ''thrust augmentation''. Other designs includes ramjets or even a complete turbojet engine. Some, known as ''rocket-on-rotor'' systems, involve placing rockets on the tips of the rotor blades that are fueled from a tank. If the helicopter's engine fail ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hiller YH-32 Hornet
The Hiller YH-32 Hornet (company designation HJ-1) is an American Ultralight aircraft (United States), ultralight helicopter built by Hiller Aircraft in the early 1950s. It was a small and unique design because it was powered by two Hiller 8RJ2B ramjet engines mounted on the rotor blade tips which weigh each and deliver an equivalent of for a total of . Versions of the HJ-1 Hornet were built for the United States Army and the United States Navy in the early 1950s. The Hiller Museum identifies the YH-32A, named the ''Sally Rand'', as the first Attack Helicopter, helicopter gunship. The Hiller HOE-1 became the first production ramjet helicopter, and the Army and Navy flew a small number of these aircraft for a short time to test and evaluate the technology. Design and development The Hiller HJ-1 Hornet was an early attempt to build a jet-powered helicopter using ramjets, with work beginning in 1948. Before that there had been experiments with the XH-26 Jet Jeep tip rotor pulse ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hiller VXT-8
The thumb is the first digit of the hand, next to the index finger. When a person is standing in the medical anatomical position (where the palm is facing to the front), the thumb is the outermost digit. The Medical Latin English noun for thumb is ''pollex'' (compare ''hallux'' for big toe), and the corresponding adjective for thumb is ''pollical''. Definition Thumb and fingers The English word ''finger'' has two senses, even in the context of appendages of a single typical human hand: 1) Any of the five terminal members of the hand. 2) Any of the four terminal members of the hand, other than the thumb. Linguistically, it appears that the original sense was the first of these two: (also rendered as ) was, in the inferred Proto-Indo-European language, a suffixed form of (or ), which has given rise to many Indo-European-family words (tens of them defined in English dictionaries) that involve, or stem from, concepts of fiveness. The thumb shares the following with each of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hiller UH-12
The Hiller OH-23 Raven is a two, three, or four-place, military light observation helicopter based on the Hiller Model 360. The Model 360 was designated by the company as the UH-12 ("UH" for United Helicopters), which was first flown in 1948. Initially it was a two-place helicopter powered by a piston engine that entered service in the late 1940s, it went on to be a popular military and civilian light helicopter in the late 20th century. A Hiller UH-12 was the first helicopter to make a transcontinental flight across the USA, in 1949. It served in the Korean War with U.N. forces and also in Vietnam. It was an important early helicopter and was widely used internationally, in U.K. service it was called the Hiller HT Mk 1 and Mk 2, and the U.S. Navy also used it as the HTE-1 for training. It was sold commercially as the UH-12 (This was a company designation not military), though some military operators used the company designation. Some later models were designed for turbine pow ...
