Found this today, about : AEROM: NASA’s Unsteady Aerodynamic and Aeroelastic Reduced-Order Modeling Softwar

With studies on wind tunnel models of the JAS 39 Gripen :

AEROM: NASA’s Unsteady Aerodynamic and Aeroelastic Reduced-Order Modeling Software

The origins, development, implementation, and application of AEROM, NASA’s patented reduced-order modeling (ROM) software, are presented. Using the NASA FUN3D computational fluid dynamic (CFD) code, full and ROM aeroelastic solutions are computed at several Mach numbers and presented in the form...

I read that direct side force control was considered and mentioned fairly late in the development in the aircraft. What happened?

Hi,


here is the SAAB-2111 and some alternative designs for Gripen.

Did Saab invent the LEVCONs?!

There were quite a lot of leading edge vortex flap schemes explored in US and UK in the 70s/80s, some of which had apex flaps like this.
