Book Description
Use of a normal-shock positioning control was demonstrated at Mach numbers of 1.8 and 2.0 for a translating-spike supersonic inlet in combination with a J34 turbojet engine. Stabile operation of the control was obtained which can be partly attributed to a nonlinearity in the servo valve in the null region.

Book Description
A method is presented to design a supersonic inlet that will match turbojet-engine air mass-flow requirements over a wide Mach number range. Two types of bypasses were investigated; one had a 360 degree annular cowling and the other had twin slotted ducts. Three models were flight tested. Two of the models, which had bypass ducts, were also ground tested. The bypass models had higher external drags. Both bypass models approximated a typical turbojet-engine air mass-flow requirement between Mach numbers 1.0 and 2.0. The flight tests covered a Reynolds number range from 200,000 to 800,000 and a Mach number range from 0.8 to 1.95.

Book Description
A normal-shock positioning control which utilized the bypass of a supersonic inlet to set the required air flow for a J34 turbojet engine was investigated to Mach number 2.0 in the Lewis 8- by 6-foot supersonic tunnel. A small static probe extending from the cowl was used to position the normal shock slightly ahead of the cowl lip and gave subcritical inlet operation. Continuous control was provided through a hydraulic servoactuator.
