The first one resembles the D-181:From Air Force 1957,
I can't ID these two projects ?.
The second one could be an early variation of the D-188 program, which used deflected stream (contrary to the D-188B which used tilt-rotors instead). I have an undefined Bell VTOL project with the same fuselage configuration but deflection in wingtip pods (the one in your image probably used deflection under the fuselage).
That weapons installation means that they Luke need Roland and apply the rotor brake before launching any missiles.Was that a real project ?,so weird !.
