The Garrett ATF3 (US military designation F104) is a 3-spool turbofan engine developed at the California division of Garrett AiResearch. Due to mergers it is currently supported by Honeywell Aerospace. The engine's design is unusual; the core flow path is reversed twice.
A chassis dynamometer, informally referred to as a rolling road [1] or a dyno, is a mechanical device that uses one or more fixed roller assemblies to simulate different road conditions within a controlled environment, and is used for a wide variety of vehicle testing and development purposes.
Single-engine light aircraft fuel tanks are usually in the wings, but some aircraft have a small "header tank" between the normal fuel tank and the engine, to facilitate reliable fuel flow to the engine. On many small or very old single-engine header tanks (and even main tanks) are often mounted above and/or immediately behind the engine. A few ...
A fuel control unit attempts to solve those problems by acting as an intermediary between the operator's controls and the fuel valve. The operator has a power lever which only controls the engine's potential, not the actual fuel flow. The fuel control unit acts as a computer to determine the amount of fuel needed to deliver the power requested ...
On July 19, 2006 Rocketdyne announced that the demonstrator engine front-end had been operated at full capacity. [3]According to NASA, the Integrated Powerhead Demonstrator project was the first of three potential phases of the Integrated High Payoff Rocket Propulsion Technology Program, which was aimed at demonstrating technologies that double the capability of state-of-the-art cryogenic ...
The inputs are received by the EEC and analyzed up to 70 times per second. Engine operating parameters such as fuel flow, stator vane position, air bleed valve position, and others are computed from this data and applied as appropriate. FADEC also controls engine starting and restarting.
Turbocharged with a FADEC control system using Lycoming's iE2 system, offering independent Electronic sensors and fuel injection controls for each cylinder, which manage detonation and exhaust gas temperature, make the engine compatible with a range of fuel compositions, producing up to 375 hp (280 kW).

A load cell transducer can be substituted for the scales in order to provide an electrical signal that is proportional to torque. Another means to measure torque is to connect the engine to the dynamo through a torque sensing coupling or torque transducer. A torque transducer provides an electrical signal that is proportional to the torque.
