Popis: A test was conducted to measure the time-averaged flow rate of a pulse detonation engine. The objective of this flow test was to determine the flow effectiveness of a pulse detonation engine utilizing a rotating spool of tubes. Since thrust is directly proportional to flow, the ability of the device to pass flow at operating rotational speeds is critical to its ability to create thrust. The flow effectiveness at the interface between the statically mounted tubes and the rotating spool of tubes is driven by the time- varying open area of the tubes and the flow coefficient at the interface. This test measured the flow coefficient for variations in the time-varying open area at the interface resulting from various tube diameters and rotational speeds. While the rotational speed of the detonation tubes did affect the flow effectiveness at the tube/tube interface, the effect was minimal and does not limit the feasibility of a pulse detonation engine.
