F-15 Speed Brake Development

Scan0333Scan0334Untitled 1bUntitled 2a One of the three main visual differences between pre-production and production aircraft is the length of their speed brakes. Short for pre-production and long for production. Jack Abercrombie (Former McAir Chief Aerodynamicist) has written a great article on the history of the F-15 speed brake development.

BTW: The other two are the clipped wing tips (covered below) and the notched horizontals.

Does the speed brake have a blow back check valve or the flaps?

Hello Ron,
Thanks for your Flight Manuals. They are a good source for so much stuff not found elsewhere.
Are you able to help with access to the speed brake article? The click doesn't work.
Best regards Peter

I recently read a report on the effect of airbrake extension on fin buffet on Euro Typhoon. Since the position is similar to F-15 I wondered what the F15 story was. Now I know. Much appreciated.
