Motoring Dynamometer for Engine Development
Calibrating combustion engines is tedious and difficult to do well. It is extremely powerful to use a motoring dynamometer when performing EFI calibration as it allows all load and RPM points of the engine to be reached, including over-run (descent) conditions and low speed heavy load (starting). Motoring dynamometers can also be used to measure engine friction and the performance of absorbing devices such as pumps and alternators. The TigerDyne motoring dynamometer gives Power4Flight an outstanding ability to calibrate, characterize and test small UAV powertrains.
Combined with dual gas analyzers, a precision fuel flow meter, and temperature chamber, this facility allows for dependable determination of optimum spark advance, fueling and other calibration settings at each mapping point.
Endurance Testing Facility
Our endurance testing facility allows us to do remote engine running for endurance testing. The facility is equipped with an air exchange fan, dual cooling fans, automatic fire suppression, and remote monitoring capability for unattended 24-hour endurance runs.
Endurance testing in UAS systems is the key tool for proving the entire propulsion system design is capable of meeting the design TBO (time between overhaul). This tests not just the engine, but the fuel system, isolation mounts, wiring, and starter generator systems.
Engine Testing Trailer
The engine testing trailer provides a mobile space to perform engine testing, allowing tests at different altitudes as the entire test cell can be towed to altitude by a car.
The trailer has two centrifugal cooling fans which are capable of cooling test engines continuously at wide open throttle. One exhaust fan is used to replenish oxygen to the interior volume. Engine operation is controlled from a PC outside the chamber through extended communication cables.
