This may not be a real project as it says "artists concept". Might be an ancestor of HFB/Ryan HFB 530 Ranger?

Propulsion system of retractable fan concept, as illustrated above, has been tailor-made to mission requirement of aircraft. Wide latitude in configuration in sub and supersonic design includes V/STOL capability bonus. U.S.-Federal Republic of Germany have agreed on joint studies of such an aircraft.

I'm not sure that this was a "real project", either, but someone did a lot of work to provide these illustrations for AIAA Paper No. 64-196, "The Lift Fan V/STOL Concept for Future Applications", by J.M.Peterson. A small portion of the artwork appeared in the Ryan VTOL/STOL Projects topic previously.

This 1965 Ryan "Advanced Vertifan" design looks to be aimed at US/FRG project - note German markings.

Rather similar to this Boeing/EWR US/FRG study:

It's hard to think it would have made a sensible solution, thinking about the engineering challenges.
 
What intrigue me is:

Most depiction of Model 187C have Germans marking of Bundeswehr Luftwaffe !
was the Model 187 proposal for Germans for VTOL strike aircraft, the germans were looking for in end of 1960 ?
Or had Ryan team up with the German Aircraft Manufacture HFB for this stile VTOL engine ?

I would guess the answer to those questions would be "both'.
 
This design is 1965. In 1968, Ryan and HFB had been conducting joint studies for 2 years ending up with the HFB 530 / Y2A Ranger.
 
And Caravellarella posted this here which has dimensions and other stats.

Lift fans are lighter than complete engines, but you still need enough engine to drive them... 1hp produces somewhere between 2 and 5 lbs of thrust, depending on fan.
