Abstract: ABSGAM is a computer model developed to predict the maximum sortie generation capability of aircraft operating from a typical USAF air base. The model allows the user to easily change input parameters to evaluate their effect on: (1) aircraft sortie rates, (2) cumulative sorties generated, (3) payload launched, and (4) material personnel required to support the air base operation. ABSGAM simulates (1) an air-base-attack and recovery, (2) reduced payload operations, (3) reduced maintenance capability, (4) extended turn-around time, and (5) aircraft attrition (both air and ground). Program input has been minimized for ease of use. Program output is available in tabular and graphical form. This model was developed as part of a technology assessment.

Abstract: A cylindrical core of a ceramic such as alumina (Al.sub.2 O.sub.3) has grooves in the form of a double lead thread. A coil of Nichrome V is placed in the grooves, starting in one lead of the thread and returning in the other. A split ring of a ceramic such as beryllia surrounds the core. The heater is enclosed in a housing of a metal such as Inconel 600. The entire cartridge is only one inch long and 3/16 inch diameter. It is used as a catalyst bed heater for a satellite thruster.
