Computer algorithms which calculate in-flight engine and aircraft performance real-time are discussed. The first step was completed with the implementation of a real-time thrust calculation program on a digital electronic engine control (DEEC) equiped F100 engine in an F-15 aircraft. The in-flight...
In-Flight Thrust Determination as Applied to the JSF ProgramVorwerk, AmandaCiszek, R Scott
thrust characteristicsMultidimensional calculations are performed to demonstrate that, by its characteristics, the pulse detonation engine (PDE) is a unique type of ramjet propulsion system, which can be used in both subsonic and supersonic aircraft. By a number of examples, it is shown that, in ...

Differential thrust can be used for directional control on distributed electric propulsion aircraft. This paper presents an assessment of flight dynamics a
300 pounds of thrust, each. The JetStar 731 was a modification program to replace the turbojet engines with quieter, more efficient and more powerful Garrett AiResearch TFE731 turbofan engines which increased thrust to 3,700 pounds per engine. New production JetStar II airplanes were equipped ...
suspended under the wings in two-engine pods. The J47 is a single-shaft axial-flow turbojet engine with a 12-stage compressor section, 8 combustion chambers, and single-stage turbine. The J47-GE-19 was modified to run on gasoline and was rated at 5,200 pounds of thrust (23.131 kilo...
An Airplane Performance Control System: A Flight Experiment Pilot performance and preference measures were obtained for 12 pilots in actual flight operations using a twin-engine general aviation aircraft with both conventional controls and a Performance Control System (PCS). The PCS provides zero... ...
Since taking flight, insects have undergone repeated evolutionary transitions between two seemingly distinct flight modes1,2,3. Some insects neurally activate their muscles synchronously with each wingstroke. However, many insects have achieved wingbeat frequencies beyond the speed limit of typical neuromu...
It was rated at 6,000 pounds of thrust (26.69 kilonewtons). It weighed 2,400 pounds (1,089 kilograms). VN799 was the first British airplane built with an axial-flow turbojet engine. VN799, flown by Flight Lieutenant Harry Maule with Scientific Officer I Mike Burgan, crashed at Sutton ...
