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.
Other organizations generally considered reputable, such as the American Automobile Association and Consumer Reports have performed studies with the same result. [ 3 ] [ 4 ] One reason that ineffective fuel-saving gadgets are popular is the difficulty of accurately measuring small changes in the fuel economy of a vehicle.
Jul. 2—Mayo Clinic Health System in Albert Lea recently received new electrophysiologic equipment, called an Eclipse. The clinic got the equipment in April with the help of the Naeve Health Care ...
Detuner is a generic term for a jet engine test cell exhaust system muffler. Aircraft jet engine testing facilities typically require a means to vent and dampen the engine exhaust. The engine exhaust flow is "augmented" with a relatively large flow of cooling air induced by a Venturi effect into the exhaust silencing system, so the exhaust ...
Test cycles specify the conditions under which the engine or vehicle is operated during the emission test. There are many different test cycles issued by various national and international governments and working groups. [1] Specified parameters in a test cycle include a range of operating temperature, speed, and load. Ideally these should ...
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.
The AEDC Sea Level Test Cells, located at Arnold Engineering Development Complex, is a collection of test cells used to economically perform durability testing on large augmented turbine engines at near sea level conditions. All test units in the facility are owned by the United States Air Force and currently operated by National Aerospace ...
The subsequent 143-page report (PB 211-015, available from NTIS) reviewed a series of actual handling tests designed to evaluate the handling and stability under extreme conditions; a review of national accident data compiled by insurance companies and traffic authorities for the cars in the test—and a review of related General Motors ...
