Convair XFY-1 Pogo
[First released on 03/Jun/2001 - Current version 5.41.00]


In 1948, the Navy organized a formal study for a VTOL fighter based on information derived from project Hummingbird and from captured German documents pertaining to the Focke-Wulf Triebflugel ramjet fighter. The Navy's VTOL fighter was to be housed in a vertical tepee type structure aboard most all ships. The new fighter would be launched once a radar threat was known and then be radar guided to intercept the attackers.

Convair's XFY-1 was designed around the Allison YT-40 coupled engine. The YT-40 was created by marrying two T-38 turboprop engines into a single gearbox to drive the counter-rotating propellers.

Armament was to be either two or four 20 mm guns or forty-eight folding fin rockets located in wing tip pods, a feature never installed or tested. Wing tip and vertical tail pods also housed the four caster type landing gear.

All its textures was originally made by me and it sports the prototype scheme plus a flight testing uniform for the pilot.


 

Specifications (from the manufacturer):

Power Plant: 2 engines T-38 coupled (the YT-40 which totalized 5,850 sHp)
Fuel capacity: 4,000 lb (estimated)
Weight empty: 13,000 lb
Weight full: 16,250 lb
Wingspan: 25 ft
Length: 34 ft
Endurance: unknown
Maximum ceiling: 43,700 ft
Maximum speed: 500 kt

During the modeling of this aircraft I developed a valuable technique that permits the rendering of different textures for each engine's nacelles. You can see it showed at the graph below in this page's bottom and also detailed in the advanced techniques tutorial section.





Homage to "Skeets" Coleman

I got another accomplishment in the modeling of this X-Plane aircraft, that was really acid to do, in providing the model with an open canopy and the pilot's figure. I thought doing this both as a homage to Pogo's pilot, Coleman, and also to develop my modeling skills. I named my virtual pilot "Included" for obvious reasons :)

"Skeets" Coleman was the first pilot to ever takeoff vertically, transition to horizontal flight and land in a VTOL aircraft.


 

Coleman climbed the airplane to 10,000 ft on February 5, 1955. At this altitude during winter, temperatures can drop to freezing, yet he never closed the canopy once, during the entire time he flew the XFY-1.

Convair installed an ejection seat but everyone thought it unreliable and technicians disarmed it. If serious trouble occurred in flight, his only option was to "step over the side" but it was considerably easier to leave the plane if the canopy was already open.



You can see in this blown-up view that nacelle 1 and nacelle 2 are different both in shape and in textured applied.

Also do notice that the pilot is indeed part of the nacelle 2 modeling.

  The canopy was rendered open to permit the escape of the pilot. The cockpit's interior isn't empty and there are side walls, back, floor, instruments panel, the two-sided frontal canopy and also a control stick.
