Hodder and published by . This book was released on 1970 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: The low-speed aerodynamics of a large-scale triangular wing model, with a reduced thickness, tip-turbine driven lift fan in each wing were investigated in the Ames 40-by 80-Foot Wind Tunnel. The model had a 5-percent-thick wing typical of wings designed for supersonic performance. Conventional lift-fan depth has, in the past, limited wing thickness to about 10 percent. A thinner lift fan for the present investigation was obtained by modification of a conventional fan. The modification included removing the discharge stator and reducing the fan inlet length and radius. To control airflow separation resulting from small inlet radii, blowing boundary-layer control was applied through a nozzle in the inlet. Performance of the modified fan along with aerodynamic characteristics of the total configuration is presented. The static thrust performance of the conventional fan (requiring a lo-percent wing) was equalled by the reduced thickness fans of this investigation.--P. [i].

Book excerpt: This book records the aeronautical activities of this Norfolk-based company, with a brief history of its origins by William Moore in 1797, and its work during the First World War. It pioneered metal construction after the war and produced parts for the R-101 airship. As Boulton Paul Aircraft Ltd at Wolverhampton, the Defiant was conceived, and its gun turrets would defend RAF bombers during WWII.

Available in PDF, EPUB and Kindle. Book excerpt: An analytical investigation of the dynamic performance of a centrifugal lift fan was conducted to provide an explanation for the behavior which occurred when the fan was subjected to a varying backpressure. Analysis of test data shows that the fan response del Q/del P can be represented by a first-order lag system. An in-depth analysis of the various elements of the lift fan system revealed that the inertia of the air within the fan was the primary contributor to the observed fan bahavior. The analysis further showed that variations in fan speed would not produce the behavior measured in the test and that the response due to the compliant properties of air within the fan occurs at a frequency that is much higher than the frequency range of the test. A time-domain digital computer program has been developed which integrates the rate of change of fan flow with a varying backpressure. Good correlation is exhibited between test data and the computer predictions at all frequencies. (Author).
