F11F Tiger/F11F-1F Super Tiger
« on: July 05, 2012, 05:17:19 AM »

F11F

Design and development:

The F11F (F-11) Tiger origins can be traced back to a privately funded 1952 Grumman concept to modernize the F9F-6/7 Cougar by implementing the area rule and other advances. This Grumman company project was known as the G-98, and by the end had departed totally from the Cougar.


An early production "short nose" F11F and a later "long nose" from VT-23.
The design's potential for supersonic performance and reduced transonic drag stirred interest in the Navy. By 1953, redesigns led to a completely new aircraft bearing no more than a familial resemblance to the Cougar. The new wing had full-span leading edge slats and trailing edge flap with roll control achieved using spoilers rather than traditional ailerons. For storage on aircraft carriers, the F-11 Tiger's wings manually folded downwards. Anticipating supersonic performance, the tailplane was all-moving. The aircraft was designed for the Wright J65 turbojet, a license-built version of the Armstrong Siddeley Sapphire.[1]
The Navy Bureau of Aeronautics was sufficiently impressed to order two prototypes, designated XF9F-8 even though the new fighter was clearly a new design. To add to the confusion, the prototypes were then redesignated XF9F-9 with the XF9F-8 designation going to another more straightforward Cougar derivative. Since the afterburning version of the J65 was not ready, the first prototype flew on 30 July 1954 with a non-afterburning engine. In spite of this, the aircraft nearly reached Mach 1 in its maiden flight. The second prototype, equipped with the afterburning engine, became the second supersonic US Navy aircraft, the first being the Douglas F4D Skyray. In April 1955, the aircraft received the new designation F11F-1 (F-11A after adoption of the unified Tri-Service naming system in 1962). Carrier trials started on 4 April 1956 when an F11F-1 Tiger landed on and launched from USS Forrestal.[2]
The F-11 Tiger is noted for being the first jet aircraft to shoot itself down.[3] On 21 September 1956, during a test firing of its 20 mm (.79 in) cannons, pilot Tom Attridge fired two bursts mid-way through a shallow dive. As the velocity and trajectory of the cannon rounds decayed, they ultimately crossed paths with the Tiger as it continued its descent, disabling it and forcing Attridge to crash land the aircraft; he survived.

Variants

VF-33 Tigers from USS Intrepid in 1959.
YF9F-9
Original designation.
F11F-1
Single-seat fighter version for the U.S. Navy, re-designated F-11A in 1962. 199 built and later production aircraft had a longer nose. One was used for static test and a further production of 231 aircraft cancelled.
F11F-1P
designation of a Navy photo reconnaissance version, 85 were cancelled.

F-11F-1 (Super Tiger)

Design and development

In addition to the F-11A (F11F-1) fighter, Grumman also proposed a more advanced version of the airframe known as the F11F-1F Super Tiger. This was the result of a 1955 study to fit the new General Electric J79 engine into the F-11 airframe. The Navy was sufficiently interested to authorize modification of two production F11F-1s with enlarged air intakes and YJ79-GE-3 turbojets, with the result being designated the F11F-1F, indicating a production F11F-1 with a special engine fit.
The aircraft first flew on 25 May 1956, reaching Mach 1.44 in one of the flights. After addition of 60° wing root fillets, a 13.5 in (35 cm) fuselage extension, and an uprated J79 engine, the F11F-1F reached an impressive Mach 2.04. This was a surprise even to Grumman, which had expected a top speed of only Mach 1.4 at altitude.[1] By comparison, the F11F-1 with the Wright J65 had had difficulty exceeding Mach 1.1. However, the U.S. Navy did not order the Super Tiger into production. Although the service ceiling of the aircraft was nominally 59,000 feet, a test flight on 18 Apr 1958 at Edwards AFB set a world altitude record of 76,938 feet.

Operational history (Marketing efforts)

Having failed to secure the Navy contract, Grumman marketed the Super Tiger to foreign customers. The Super Tiger outperformed the Saab Draken, Lockheed F-104 Starfighter, Dassault Mirage III and Fiat G.91 in a tender to equip the Swiss Air Force. The Mirage III was finally chosen as a cheaper and more secure alternative, yet a close second in terms of performance.[2][3]
The German Luftwaffe, Japan Air Self Defense Force and Royal Canadian Air Force showed considerable interest but eventually the Lockheed F-104 Starfighter was chosen. This outcome, however, was marred by the Lockheed bribery scandals, in which huge sums were paid by Lockheed to influential politicians in those countries to ensure the adoption of the Starfighter.

NOTICE
i didnt add any pictures of the Super Tiger, because its a normal tiger airframe with a J79-GE-3A engine, so the 3d would be pretty much exactly the same.

+1000..................

VF-51 is in that list, and we can always use a plane with a Tail Hook on it...............

Beat ya Razor!.....................   :P

Good idea for a request. I've always had a soft spot for this one too. The normal Tiger would give the MiG-17s a good run for their money, and the Super Tiger could probably handle a MiG-21. It sure is purdy too.

yeah. the super tiger could out perform the Mirage III and the F-104, so the MiG-21 would probably be no match for a super tiger with a decently skilled pilot.

Plus it's one of the first jet planes to shoot itself down! I'd support one of these!

Besides it could double for the Mirage F-1 with a nice Skin hack.

Oh yeah, bring it...
I consider the Tiger the first "modern" looking fighter...
