Abstract:

An investigation was made of the feasibility of installing a high lift boundary layer control BLC system in a YCV-2B airplane. Work was conducted to determine the feasibility and practicability of improvement of takeoff and landing performance of YCV-2B aircraft. Primary effort was directed to the development of a compressed airgasoline fuel primary motor for driving the jet pump system. Secondary effort was directed to the design and evaluation of the system and to the performance characteristics. Also, smoke tunnel tests were conducted to determine qualitatively the effects of BLC on lift characteristics of the YCV-2B airfoils. Difficulty was experienced in the development of the primary motor owing to its inability to contain high temperatures. However, the experimental prototype model was satisfactory for obtaining limited jet pump data. The performance of the jet pump was not able to improve takeoff and landing characteristics of the aircraft. Design and technical analysis studies showed that the BLC system could not be installed and operated in the YCV-2B airplane with any reasonable expectancy of success. Included are equations, computer programs and methods for predicting design parameters, and performance characteristics of jet pumps and boundary layer controls systems.
