Now,we can say about this contest,maybe the tenders were;

- North American CL-4035 (T2J-1 VTOL)
- Ryan/GE Model-? ,sure was in
- Douglas D-793
- Grumman G-260 ,sure was in,it had a fan lift in center inboard section of the wing

Browsing through an old index of blueprints (probably from SDASM) I've just come across the mention of a VTO-Executive variant of the Vertifan, also under the Model 143 designation. The closest thing I've found to this description in my files is this Vertifan project, but I can't say for sure if it's just that, or another project of the same era.

From AW 1960,

I think this aircraft was intended for that competition;

In the Flying magazine article it mentions "rotating engines," a term I have not seen before. Can anyone shed some light on this?
 
I was looking through some articles on "The Drive", and I found this:


Hopefully it hasn't been posted here already, if it has, I ask the moderators to delete this post.

From Vertiflite,

the first time to know that,North American co-operated with Ryan to
develop V/STOL Transport and Interceptor designs,based on this
concept ?.

Where there some German Connection for Vertifan ?

Ryan Model 190 is based on F-104G (G for Germany)
Next if found two picture that show Aircraft that look like Model 187b
one of the aircraft has Luftwaffe Marking

Wow thanks. Fan stream was too hard to resue pilot.
It's the same idea of Mcdonnell Douglas Joint Strike Fighter lift fan concept.
F-35B's lift fan is shaft drive.
As proposed, the McDonnell Douglas entry into the JSF competition used a lift system consisting of vectored thrust from the main engine + a lift engine. I've been told by a Boeing-St. Louis engineer (former McDonnell Douglas) that the USMC had pushed for a tip-driven lift fan approach but that McD couldn't make the ducting work in the available volume. The lift engine proposal was reportedly seen by the USMC as something of a betrayal after decades of partnership on the Harrier since it seemed to anticipate the abandonment of the Marines' V/STOL variant. The lift engine approach is less-than-ideal for the V/STOL operator (an engine and supporting systems that are dead weight in forward flight, probable lower reliability, additional maintenance and logistics burdens) and, of the possible configurations, would be most easily converted into a conventional aircraft by their removal.
 
From Vertiflite 1961,

what was this Ryan V/STOL Strike and Reconnaissance Project ?.

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.

Source:
Flying Review International, August 1965
Even by 1965, long-range SAMs had replaced point defense interceptors...



PS Everything I do / read etc in this field further reinforces my opinion that the Harrier is a work of genius.
It's certainly a work of art in how simply they achieved VTOL.

It's just kinda too bad that they never did make a straight-flow version of the Pegasus, I've seen reports of upwards of 28,000lbs thrust without water injection or afterburners for such a design! The afterburning cousin design, the BS100, made 39,500lbs thrust in AB.

Even more fun, the Pegasus is 48" in diameter, just like the TF30 and F110: Imagine an F-14 with two of those engines!



Either that or they were still looking for a way around the Key West Agreement
Definitely still looking for a way around Key West. The Army is STILL looking for a way around Key West, but they can't lobby Congress to save their lives. I think if a new version of the law gets passed, it needs to make everything subsonic officially part of the Army's remit.


=====
I wonder: Are modern engines enough lighter and more efficient that we could make a vertifan A4 and still have any range left?
 
Years ago I advocated an E-Launch cradle for Marines VSTOL: the cradle could do the trick here.
The funny side is that you could even tether and plug it onto a city network.

From Jane's all the World's Aircraft 1962-63.

THE GENERAL ELECTRIC X353-5
CONVERTIBLE LIFT FAN SYSTEM


The X353-5 lift fan system is designed to provide propulsion for VTOL aircraft through the lift, hover, transition and horizontal flight phases. The system has three basic components, comprising the lift fan, the diverter valve and a J85 turbojet engine which serves as a gas generator for the vertical phase and as a conventional turbojet for horizontal flight.

The system can be installed either in the wings of an aircraft or in the fuselage. Extensive full-scale static and wind tunnel testing has demonstrated its mechanical integrity and predicted performance. The diverter valve, which directs gas flow from the turbojet to the fan turbine, was developed in a separate programme that included hot gas testing.

The X353-5 is used in the “fan-in-wing” Ryan XV-5A VTOL research aircraft (which see).
By replacing the diverter valve with an elbow and removing the exit louvres, the X353-5 can be used as a pure lift engine.
The fan can be used with several gas generators without compromising system simplicity or performance.

Available details of the X353-5 are as follows.

BASIC GAS GENERATOR.-- A standard J 85-GE-5 turbojet, used without afterburner. Fixed conical nozzle mounted at rear of engine.
DIVERTER VALVE.-- Directs gas flow from turbojet to tip-driven turbine.
SCROLL.-- Hot gas flow enters circular scroll inlet and is split into two arms of the scroll, where gas is directed at blades of the power turbine.
POWER TURBINE.-- Tip-turbine blades mounted on rim of fan are driven by turbojet exhaust gases, turning the large coaxial fan.
FAN.-- Single-stage, with tip speed of 720 ft./sec. (220 m./sec.). Variable exit louvres control direction of airflow for hover, transition from vertical to horizontal flight or vice versa, and acceleration, louvres close during normal cruising flight to present a smooth wing surface. Fan pressure ratio l-1 : l. Fan air flow 535 lb (243 kg) sec.
DIMENSIONS.--
Fan installed dimension (distance between wing spars) 76 in. (l-93 m)
Fan tip diameter 62-5 in. (1-59 m)
Fan max. thickness 14-4 in. (0-366 m)
WEIGHT.--
Dry, including fan, diverter valve and gas generator 1,145 lb (520 kg)
PERFORMANCE RATINGS.--
Lift thrust 7,430 lb (3,370 kg)
Horizontal thrust 2,580 lb (1,170 kg)
SPECIFIC FUEL CONSUMPTIONS.--
Lift thrust 0.34
Horizontal thrust 0.98
