In December 2014, NASA awarded Lockheed Martin a contract to study the feasibility of building the SR-72's propulsion system using existing turbine engine technologies, The $892,292 (~$1.13 million in 2023) contract funded a design study to determine the viability of a TBCC propulsion system by combining one of several current turbine engines, with a very low Mach ignition Dual Mode Ramjet (DMRJ).
The Pratt & Whitney J58 (company designation JT11D-20) is an American jet engine that powered the Lockheed A-12, and subsequently the YF-12 and the SR-71 aircraft. It was an afterburning turbojet engine with a unique compressor bleed to the afterburner that gave increased thrust at high speeds.
This is a list of aircraft produced or proposed by the Lockheed Aircraft Corporation from its founding as the Lockheed Aircraft Company in 1926 to its merging with Martin Marietta to form the Lockheed Martin Corporation in 1995. Ordered by model number, Lockheed gave most of its aircraft astronomical names, from the first Vega to the C-5 Galaxy.
A trip from Chicago to Tokyo (10,123 kilometers) would take 18 skips, or 72 minutes. It was planned to use hydrocarbon-based engines outside the atmosphere and experimental jet engine technology. [ 9 ] and in 2002 it was combined with the USAF X-41 Common Aero Vehicle to form the FALCON program.
Many J79-derived engines have found uses as gas turbine power generators in remote locations, in applications such as powering pipelines. The J79 has two commercial derivatives: CJ805 -3 (a non-afterburning engine, fitted with thrust reverser and sound suppressor), and the CJ805 -23 (with a free-wheeling aft fan and thrust reverser) fitted to ...
Lockheed Martin SR-72, a proposed hypersonic airplane under development by Lockheed Martin State Route 72, several highways numbered 72 in the US Topics referred to by the same term
The Pratt & Whitney J58 (JT11D-20) turbojet aero engine, which had a specific fuel requirement; namely JP-7 turbine fuel.. Turbine Fuel Low Volatility JP-7, commonly known as JP-7 (referred to as Jet Propellant 7 prior to MIL-DTL-38219 [1]) is a specialized type of jet fuel developed at Pratt and Whitney by master chemist Clarence Brown CB Eichman in 1955 for the Central Intelligence Agency ...
The Garrett TFE731 (now Honeywell TFE731) is a family of geared turbofan engines commonly used on business jet aircraft. Garrett AiResearch originally designed and built the engine, which due to mergers was later produced by AlliedSignal and now Honeywell Aerospace.
