Lockheed J37
The Lockheed J37 (company designation L-1000) was one of the first turbojet engines designed in the United States.Norton 2008, p. 221. It was not considered very important when its development was first begun in the 1930s, and it was allowed to languish. By the time it was developed enough for production use, other engines, some British-derived, had surpassed it in performance. The design was later converted to a turboprop, the T35 and still later sold to Wright Aeronautical, where it saw some interest for use on what would become the B-52 Stratofortress, before that design moved to jet power. The J37 and T35 were built to the extent of a number of testbed examples but never entered production. Design and development In 1930, Nathan C. Price joined Doble Steam Motors, a manufacturer of steam engines for cars and other uses. Over the next few years he worked on a number of projects and starting in autumn 1933 began working on a steam turbine for aircraft use. The engine feat ...

Frank Whittle
Air Commodore Sir Frank Whittle, (1 June 1907 – 8 August 1996) was an English engineer, inventor and Royal Air Force (RAF) air officer. He is credited with inventing the turbojet engine. A patent was submitted by Maxime Guillaume in 1921 for a similar invention which was technically unfeasible at the time. Whittle's jet engines were developed some years earlier than those of Germany's Hans von Ohain, who designed the first-to-fly (but never operational) turbojet engine. Whittle demonstrated an aptitude for engineering and an interest in flying from an early age. At first he was turned down by the RAF but, determined to join the force, he overcame his physical limitations and was accepted and sent to No. 2 School of Technical Training to join No 1 Squadron of Cranwell Aircraft Apprentices. He was taught the theory of aircraft engines and gained practical experience in the engineering workshops. His academic and practical abilities as an Aircraft Apprentice earned him a place ...

Tizard Mission
The Tizard Mission, officially the British Technical and Scientific Mission, was a British delegation that visited the United States during WWII to obtain the industrial resources to exploit the military potential of the research and development (R&D) work completed by the UK up to the beginning of WWII, but that Britain itself could not exploit due to the immediate requirements of war-related production. It received its popular name from the programme's instigator, Henry Tizard. Tizard was a British scientist and chairman of the Aeronautical Research Committee, which had propelled the development of radar. The mission travelled to the US in September 1940 during the Battle of Britain. They intended to convey a number of technical innovations to the US to secure assistance in maintaining the war effort. Objectives The objective of the mission was to cooperate in science and technology with the U.S., which was neutral and, in many quarters, unwilling to become involved in the war. ...

Lockheed L-133
The Lockheed L-133 was an exotic design started in 1939 which was proposed to be the first jet fighter of the United States Army Air Forces (USAAF) during World War II. The radical design was to be powered by two axial-flow turbojets with an unusual blended wing-body canard design capable of 612 mph (985 km/h) in level flight. The USAAF rejected the 1942 proposal, but the effort speeded the development of the USAAF's first successful operational jet fighter, the P-80 Shooting Star, which did see limited service near the end of war. The P-80 was a less radical design with a single British-based Allison J33 engine, with a conventional tail, but it retained a wing which was the same shape as the outer wing sections of the P-38 Lightning. Development The Lockheed aviation company was the first in the United States to start work on a jet-powered aircraft. The L-133 design started in 1939 as a number of "Paper Projects" by engineers Clarence L. "Kelly" Johnson, Willis M. Ha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Compressibility
In thermodynamics and fluid mechanics, the compressibility (also known as the coefficient of compressibility or, if the temperature is held constant, the isothermal compressibility) is a measure of the instantaneous relative volume change of a fluid or solid as a response to a pressure (or mean stress) change. In its simple form, the compressibility \kappa (denoted in some fields) may be expressed as :\beta =-\frac\frac, where is volume and is pressure. The choice to define compressibility as the negative of the fraction makes compressibility positive in the (usual) case that an increase in pressure induces a reduction in volume. The reciprocal of compressibility at fixed temperature is called the isothermal bulk modulus. Definition The specification above is incomplete, because for any object or system the magnitude of the compressibility depends strongly on whether the process is isentropic or isothermal. Accordingly, isothermal compressibility is defined: :\beta_T=-\frac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
