Dr. Daniel P. Raymer is an aircraft designer that used to work for Rockwell International. He wrote a book about aircraft design called Aircraft Design: A Conceptual Approach. It was basically a textbook explaining the fundamentals of the field as well as providing equations relevant to design and aerodynamics.

In the back of the book, he provided two examples of conceptual design: one was a prop-driven stunt plane and the other was a lightweight supercruising fighter jet. I thought the supercruise jet looked cool, so I decided to draw a colored schematic of it as shown here. It was never built nor even a serious project, but I thought it looked nice enough.

The Lightweight Supercruise Fighter (LSF) is a copyright of Dr. Daniel P. Raymer.

DATA:

Length: 45 feet, 2 inches
Take-off Gross Weight: 16,480 pounds
Military Thrust: 13,776 pounds*
Full Afterburner Thrust: 16,150 pounds
Maximum Speed: over Mach 1.8
Supercruise Speed: over Mach 1.4
Nozzle Type: 2D Pitch-vectoring
Tail Type: Variable-dihedral V-tail

*I derived the dry/military thrust from a place in the book where its cruise was descrbed. The speed listed was Mach 1.4 (around supercruise speed) and it stated the thrust used was 85.3%. I inferred this to be the percent of full thrust that dry thrust represented.

Looks like F-16 meets F-22 meets MiG-29 meets Sepecat Jaguar.

That's quite a mix, huh?

This should be the "children" of an F-16 and F-22 =)

Or perhaps YF-23 due to the V-tail.

"Could be", not "should be"...

For me it looks like the children of an F-16 and a F-18 :D

Very nice indeed :D

however i'd like to know the dry thrust value of the engine :D , since for a Supercruise regime of flight, the engine must be able to bring the plane supersonic in just full military power .

I don't know if it was listed. If I find it, I'll list it.

Well, I did some looking, and if I read it correctly then dry thrust is around 13,776 pounds.
