Northrop notional vectored thrust V/STOL aircraft

Hi,


I can't ID this Northrop vectored thrust V/STOL aircraft,is it a real design
or not ?,also may be the aircraft was the beginning of Navy V/STOL Type
A aircraft.

From NASA,a manned version model;

I still can't ID it ?.

May be that aircraft was N-289, a V/STOL demonstrator.

Northrop notional V/STOL model

A model was constructed and tested to supplement the analytical investigation and gain further data for use in validation and improvement of the analytical prediction techniques. The model was configured to resemble a feasible military aircraft but was designed to operate with jets of varied number and location to allow a variety of data to be generated. The test contributes new data because of extensive pressure instrumentation present on the model. These data facilitate identification of the sources of the various induced loads measured during the test.

The model is a shoulder wing configuration equipped with an external airfoil flap and a stabilator mounted on the vertical tail above the fuselage. Two vectored thrust engines are contained in large nacelles mounted beneath the wing adjacent to the fuselage; a single lift engine is mounted within the body and forward of the vectored exits.

Please note that this is only a notional, or "theoretical" project, since it was never meant by Northrop to become a real program, but was only "made to resemble a feasible military aircraft" in test-model form "to gain further data" for later programs.
