Eighth Partial Report on the Pulse-Jet Engine Whirling Arm

reportActive / Technical Report | Accesssion Number: AD1214968 | Open PDF

Abstract:

A whirling arm, 26 feet in diameter, has been constructed and operated the Naval Research Laboratory, Chesapeake Bay Annex. Two engines are mounted on the arm, one on each end of the single blade. The engines are started and operated by remote control. The whirling arm permits operation of the pulse-jets under free-flight conditions and provides a means for obtaining data of engine characteristics. The drag of the arm is determined from empirical data and a formula is derived for the drag value at any speed.
