Lockheed’s New STOL Airlifter Design
http://defensetech.org/2011/09/15/lockheeds-new-stol-airlifter-design/

The four-engine plane (though I only see two in these pictures), called the Speed Agile Concept Demonstrator, is Lockheed’s part of an Air Force Research Lab effort to develop designs for a STOL tactical transport jet capable of operating from short and unprepared landing strips around the world. Boeing is apparently also in on the effort.

A 23 percent-scale turbofan-powered model of Lockheed Martin’s Speed Agile powered-lift STOL airlifter concept for AFRL was tested in the National Full-Scale Aerodynamics Complex at NASA Ames Research Center in California. This consolidation effort brings together experts in scramjets engines, alternative fuels, unmanned vehicles, hypersonic vehicles, collision avoidance, and aircraft energy optimization.

I think under-wing air intakes will be disastrous for the STOL Airlifter. The above wing diagrams are much better to prevent debris on take-off from entering the inlets.

The 'issue' with over-wing engine inlets is the fact that the high angles of attack used for STOL operations often shrouds the inlets causing diminished performance at a minimum to complete compressor stall and flame out at the worst.

Most STOL designs have inlets mounted forward of the wing to avoid this. However the exhaust of the engine is beneficial to be run over the wing as it can be used to create lift without actual airflow over the airframe.

Here are two versions of the Antinov AN-72/74 which is an STOL design. The AN-72/74 is the version with the forward mounted engines that exhaust over the wings and the more conventional pylon mounted engines below the wing is the AN-TK74-300 which gives up STOL in favor of increased range and reduced fuel burn.

As you can see Lockheeds design uses the best of both worlds, forward mounted semi-pylon mounted engines which are ducted to overwing exhausts to supplement the airflow over the wing to help increase the usable angle of attack before stall by accelerating the airflow at the back of the wing minimizing the possibility of flow separation.
