Flight Investigation of the Cooling Characteristics of a Two-row Radial Engine Installation


Book Description

Flight tests have been conducted to determine the cooling characteristics of a two-row radial engine at altitude in a twin-engine airplane and to investigate the accuracy with which low-altitude cooling-correlation equations can be used for making cooling predictions at higher altitudes. The test engine was operated over a wide range of condtions in level flight at density altitudes of 5000 and 20,000 feet.

Standard Procedures for Rating and Testing Multistage Axial-flow Compressors


Book Description

In order to establish a standard procedure for rating and testing multistage axial-flow compressors, the NACA Subcommittee on Compressors appointed a panel to write such a procedure. This panel made recommendations for standardization of test setups, instrumentation, test procedure, data to be taken, and the presentation of the data. These recommendations are presented.
