F-16 Question

Sun Jan 18, 2009 8:29 pm

What do you call the lifting surfaces on either side of the F-16's fuselage (you have the chines, which extend ahead of the wing and blend into them... rearwards you have these lateral chine like surfaces on either side of the fuselage which extend all the way to the tail which mount speedbrakes on the rear -- what do you call those?)?

Strake is what you are looking for.

A strake is: #part of a boat or ship. It is a horizontal strip of wooden planking or steel plating on the exterior hull of a vessel, running longitudinally along the vessel from the stem to the stern. #a device for controlling air flow over an aircraft or automobile (especially a racing car). ...

F4wso,

Just to be clear (to avoid any confusion) The rear area on the sides of the fuselage that mount the speed brakes are still considered to be part of the strake?

I've always heard it referred to as a boom.

I hesitate to say how far back it goes. I based my answer on a Fighter Weapons School aerodynamics class from back in 1986. We only talked about the part forward of the wing leading edge. Knowing the term, I did a Google search for a definition to paste into my response.

On the F/A-18, IIRC they are called Leading Edge Extensions, or LEX's...they run from the forward wing root all the way up to the cockpit, and are perched on when ingressing or egressing the jet. The small upright fins on these surfaces are called LEX Fences.

Same here, I guess you could call it analagous to the booms that run on the outboard sides of the engines on the F-15, where the horizontal stabilizers mount.
