Abstract
Considerable developmental work is progressing on various types of jet rotor systems for helicopters. Among these are the ramjet system, and the pressure system, which are described in some detail in the paper. Application of the gas turbine for driving the compressor used in the pressure system is considered briefly, as well as use of the turbojet engine. A comparison of performance of the two principal jet-rotor systems under consideration with conventional helicopter-rotor drive is given, which indicates advantages for short-haul application over the conventional drive.
