NACA-TN-2966: Propeller-performance charts for transport airplanes
Abstract: The preliminary selection of a propeller on the basis of cruising and take-off performance for application to transport airplanes at flight Mach numbers up to 0.8 can be accomplished by the use of charts and methods ...
NACA-ARR-E5F07: Heat-transfer tests of aqueous ethylene glycol solutions in an electrically heated tube
Abstract: As part of an investigation of the cooling characteristics of liquid-cooled engines, tests were conducted with an electrically heated single-tube heat exchanger to determine the heat-transfer characteristics of an-e-2 ...
NASA-TR-D-860: Analysis of cooling limitations and effect of engine-cooling improvements on level-flight cruising performance of four-engine heavy bombe
Abstract: The NACA has developed means, including an injection impeller and ducted head baffles, to improve the cooling characteristics of the 3350-cubic-inch-displacement radial engines installed in a four-engine heavy bomber. The ...
NASA-TT-F-734: Flight of aircraft with partial and unbalanced thrust
Abstract: The problem of aircraft operation under conditions of unbalanced thrust following the failure of an engine on a multi-engine aircraft is examined. The dynamics of the divergent motion of the aircraft immediately after ...
NACA-TR-D-745: High-Speed Tests of Conventional Radial-Engine Cowlings
Abstract: The drag characteristics of eight radial-engine cowlings have been determined over a wide speed range in the NACA 8-foot high-speed wind tunnel. The pressure distribution over all cowlings was measured, to and above the ...
NASA-TM-X-73566: Interim Prediction Method for Turbine Noise
Abstract: A turbine noise prediction method for interim use in the NASA Aircraft Noise Prediction Program is selected. The method predicts the level, directivity, and one-third octave band spectra of far field turbine noise as a ...
NACA-TN-2836: Radiant-interchange configuration factors
Abstract: A study is presented of the geometric configuration factors required for computing radiant heat transfer between opaque surfaces separated by a nonabsorbing medium and various methods of determining the configuration factors ...
