Air Intake Design


This graphics shows the air intake design of the F-14 Tomcat. The idea behind this layout is, that the airflow into the engine has to be undisturbed and at subsonic speed even if the aircraft is flying at supersonic speeds! Early demonstrations with the TF30 showed that this engine was extremely sensitive to inlet imperfections. Therefore a number of ramps are placed inside the air intake and are moved by actuators to divert the airflow as desired. Also, shockwaves (snake lines) do not occur inside the airinlet due to the design.


The graphic is taken from a Grumman booklet about the F-14 Tomcat. I found this picture also in the NATOPS FLIGHT MANUAL F-14A (NAVAIR 01-F14AAA-1) and in papers handed out by a professor of the University of Technology in Aachen who teaches jet-engine design.
