THIRD SYMPOSIUM ON ADVANCED PROPULSION CONCEPTS SPONSORED BY UNITED STATES AIR FORCE OFFICE OF SCIENTIFIC RESEARCH AND THE GENERAL ELECTRIC COMPANY FLIGHT PROPULSION DIVISION CINCINNATI, OHIO OCTOBER 2-4, 1962. NASA RESEARCH ON RESISTANCE HEATED HYDROGEN JETS
Abstract
The electric propulsion scheme to be considered is the simple hydrogen heater. In this approach, hydrogen is heated by passing it through or over an electrically heated refractory metal heat exchanger prior to expansion in a nozzle. To be useful for space missions, such an engine must be capable of producing a vacuum specific impulse of the order of 1000 seconds. Fortunately with a suitable design, the required heat exchanger temperatures can be obtained. In addition to being competitive in terms of specific impulse, this propulsion approach offers other potentially attractive features some of which are high efficiency, long life and reliability, simple matching to power supply, simple starting technique, and variable thrust.
