Retractable liftfans obviously were very popular for US-german cooperative
projects. Another team was Ryan/HFB ...

Model 182 is a transonic two seat close support fighter. Powered by two non-afterburning engines of 8,200lb thrust, VTO weight 34,900lb. Lifting force provided by five 4 ft fans, two in the wings and three in the fuselage (one at the rear, and two in the front under the cockpits with side intakes). Bombs carried semi-recessed under the belly either side of the main undercarriage. M-61 Vulcan gun, terrain avoidance and fire control radars, and flight refuelling capability. Maximum speed of Mach 1.2 estimated. Short takeoffs possible to 25% over VTO weight.

Model 186C

Supersonic, powered by two reheated GE-1 engines and with VTO weight 30,000lb. The efflux from the engines is ducted to eight fans mounted in the 3.25% wings. Confguration suitable for point defence duties, with max speed of Mach 2.0. However, it has too large wetted area for low level flight, an unsuitable planform for ground attack, and insufficient span for good ferry range.

Model 187B

Designed to a similar spec as 186C, but with a conventional moderately swept wing for improved strike and ferry capabilities. Mach 1.6 maximum speed. Fans now retractable into fuselage, which allows the wings to be optimised for performance without regard to fan diameter or depth.

The writer notes that such an arrangement could be combined with VG wings, and that to give better STO performance the lift fans should be rotatable to vector thrust, thereby nicely predicting the AVS :)

From Aviation Week .08.1965 some more lift fan concepts,
for transports, including the CX-6A and a VTOL fighter.

I seem to remember seeing something about a Ryan/Learjet study of a vtol Learjet using siz or eight fans (if memory serves me correctly) in sponsons on either side of a Model 23.

Yep, that one; though I've also seen the Learjet drawings on that.  As shown, the design has a few problems, like a blocked main door.  An interesting study, too.

So it was a slow day at the office, and I got bored.  So I walked out side and got some photos of the lovely Ryan XV-5A.  Thought I would share them.  I have ~1Meg versions of these as well if anyone wants the big ones.

Thank you. It is really nice to have some good close ups of this plane.

Well,  There is a Chinook with four rotorblades per hub and a set of wings, an AH-56 Cheyanne, the YAH-63 and some other things.  If I ask permission to go into the garage... just about every type of VTOL the Army played with in the 60's and 70's.  Its a wonderful backyard.   ;D
