Tables and charts for thermodynamic calculations involving air and fuels containing boron, carbon, hydrogen, and oxygen

Description: Report presenting tables and charts of gas properties for use in thermodynamic calculations for engine cycles involving the combustion of air and any fuel or combustion of fuels containing carbon, boron, hydrogen, and oxygen. Dissociation and phase changes may be accounted for with the method presented, which does not require the presentation of separate data for each fuel-air ratio.

Theoretical Comparison of Several Methods of Thrust Augmentation for Turbojet Engines

Description: "A theoretical investigation has been made of various methods of thrust augmentation for turbojet engines. The method investigated were tail-pipe burning, water injection at the compressor inlet, a combination of tail-pipe burning and water injection, bleedoff in conjunction with water injection at the compressor inlet, and rocket assist. The effect of ratio of augmented-to-normal total liquid consumption, flight conditions, and design compressor pressure ratio on the augmentation produced by each method were determined" (p. 1).

Theoretical comparison of several methods of thrust augmentation for turbojet engines

Description: "A theoretical investigation of tail-pipe burning, water injection at the compressor inlet, combination tail-pipe burning plus water injection, bleedoff, and rocket-assist methods thrust augmentation for turbojet engines was made for an engine representative of those in current use. The effect of augmented liquid ratio on augmented thrust ratio and the effects of altitude and flight Mach number on the performance of various methods were determined. The additional take-off weight involved by the use of the different thrust augmentation methods, as well as the effect of the various thrust augmentation methods on the range of a representative aircraft was also investigated" (p. 727).

Method for determining optimum division of power between jet and propeller for maximum thrust power of a turbine-propeller engine

Description: Report presenting charts by which the jet pressure ratio that gives optimum division of power between propeller and jet for maximum total thrust power may be determined for any turbine-propeller engine with or without intercooling, reheat, regeneration, or any combination of the three modifications. The method of obtaining optimum power division is compared for two sets of conditions with two other methods that have been widely used.

Study of Jet-Propulsion System Comprising Blower, Burner, and Nozzle

Description: "A study was made of the performance of a jet-propulsion system composed of an engine-driven blower, a combustion chamber, and a discharge nozzle. A simplified analysis is made of this system for the purpose of showing in concise form the effect of the important design variables and operating conditions on jet thrust, thrust horsepower, and fuel consumption. Curves are presented that permit a rapid evaluation of the performance of this system for a range of operating conditions" (p. 1).
