The engine test cell was originally used for aircraft engines. It was about 130 feet (40 m) by 30 feet (9 m) with a height of 25 feet (8 m). It is now called the Equipment Test Chamber and is used mainly for tanks, trucks, and other equipment. The original building had small tests rooms for desert, hot, marine, and jungle conditions.
An engine test stand is a facility used to develop, characterize and test engines. The facility, often offered as a product to automotive OEMs , allows engine operation in different operating regimes and offers measurement of several physical variables associated with the engine operation.
The air intake and exhaust systems of indoor engine test cells and hush houses are designed to block the transmission of noise, while optimizing the engine air flows. The engine exhaust, after having been thoroughly mixed with cooling air, is generally discharged through a vertical stack.
Integration of the dynamometer control system with automatic calibration tools for engine system calibration is often found in development test cell systems. In these systems, the dynamometer load and engine speed are varied to many engine operating points, while selected engine management parameters are varied and the results recorded ...
At one time or another, the center has operated 58 aerodynamic and propulsion wind tunnels, rocket and turbine engine test cells, space environmental chambers, arc heaters, ballistic ranges and other specialized units. Twenty-seven of the center's test units have capabilities unmatched elsewhere in the United States; 14 are unique in the world.
Both cells can accommodate engines that produce up to 70,000 pounds of thrust. In recent years, SL-2 has tested the F100 engine for the F-15 Eagle, F-16 Fighting Falcon, and the F119 engine for the F-22A Raptor. SL-3 has also tested the Pratt & Whitney F100 engine, as well as the Pratt & Whitney F135 engine for the F-35. [1]
Opel car factory new car testing on chassis dynamometer Saab 96 on mobile dynamometer. Tractive force control/Force constant - in this mode the dynamometer holds set force regardless of speed or other parameters. The specified Force can be distributed evenly between the axles or in different amounts between different axles in the case of ...
An ATE can be a simple computer-controlled digital multimeter, or a complicated system containing dozens of complex test instruments (real or simulated electronic test equipment) capable of automatically testing and diagnosing faults in sophisticated electronic packaged parts or on wafer testing, including system on chips and integrated circuits.
