Would be nice to see a production F-16 with that inlet. Supposedly it performed better than the standard inlet.Eeehh, no. DSI intake is optimized for M up to 1.6.
How could you have possibly missed the extended arguement on Key?
"The overall inlet design, called a diverterless supersonic inlet or DSI, moved from concept to reality when it was installed and flown on a Block 30 F-16 in a highly successful demonstration program.
The new inlet showed slightly better subsonic specific excess power than a production inlet and that verified the overall system benefits of eliminating the diverter. Test pilots remarked that military power settings and thrust characteristics were very similar to standard production F-16 aircraft with the same General Electric F110-GE-129 engine. Considering the overall goal of the flight test program was to demonstrate the viability of this advanced inlet technology, the results were excellent.
The DSI bump functions as a compression surface and creates a pressure distribution that prevents the majority of the boundary layer air from entering the inlet at speeds up to Mach 2
. In essence, the DSI does away with complex and heavy mechanical systems.
The DSI concept was introduced into the JAST/JSF program as a trade study item in mid-1994. It was compared with a traditional "caret" style inlet. The trade studies involved additional CFD, testing, and weight and cost analyses. The new inlet earned its way into the JSF design after proving to be thirty percent lighter and showing lower production and maintenance costs over traditional inlets while still meeting all performance requirements."
