Engine Instruments The test cell control room contains the controls used to operate the engine and the instruments used to measure various temperatures and pressures, fuel flow, and other factors. These devices are necessary in providing an accurate check ... evaluation of the operating engine. The control room is separate from, but adjacent to, the space (test cell) that houses the engine being tested. The safe, economical, and reliable testing of modern aircraft engines depends largely upon…
- Chapter 10: Engine Maintenance & Operation › Turbine Engine Operation › Checking Takeoff Thrust
Checking Takeoff Thrust Takeoff thrust is checked by adjusting the throttle to obtain a single, predicted reading on the engine pressure ratio indicator in the aircraft. The value for engine pressure ratio, which represents takeoff thrust for the prevailing ambient ... atmospheric conditions, is calculated from a takeoff thrust setting curve or, on newer aircraft, is a function of the onboard computer. This curve has been computed for static conditions. [Figure 10-74] Therefore, for all precise thrust checking, the aircraft…

Ground Operation Engine Fire Move the fuel shutoff lever to the off position if an engine fire occurs, or if the fire warning light is illuminated during the starting cycle. Continue cranking or motoring the engine until the fire ... been expelled from the engine. If the fire persists, CO2 can be discharged into the inlet duct while it is being cranked. Do not discharge CO2 directly into the engine exhaust, because it may damage the engine. If the fire…
