TerryLeave a comment

This is a scratch built J-3 Kitten, scaled up 10% to accept an EA-81 Subaru direct drive engine with a 60 inch ground adjustable Precision propeller.

The cowling and fuel tank are fibreglass, and the airframe is covered in Ceconite and finished with Randolf dope.

It took about 3000 hrs over two years to construct, finishing in 2001.

Seversky SEV-1XP / SEV-S-1

TerryLeave a comment

The SEV-2XP with an 800hp Wright XR-1670 engine, was damaged enroute to Wright Field and hurriedly converted into the single-place SEV-1XP with an 850hp Wright R-1820-G4 Cyclone engine

First flying as the NX18Y c/n 2 still, in August 1935 piloted by de Seversky, the SEV-1XP initially retained the R-1670 engine. By now featuring a semi-retractable undercarriage, the prototype was reengined with an ungeared nine-cylinder Wright R-1820 Cyclone. This engine failed to produce its rated power, however, the predicted 483km/h maximum speed proving unobtainable in consequence.

The USAAC Materiel Division’s decision to defer fighter choice pending further evaluation to be held in March 1936 enabled the SEV-1XP to be re-engined once more, this time with an 850hp 14-cylinder Pratt & Whitney R-1830-9 Twin Wasp. This was succeeded, in turn, by a geared R-1820-G5 offering 950hp for take-off, but the Twin Wasp was subsequently re-installed.

With this last engine and an armament of one 7.62mm and one 12.7mm gun, the SEV-1XP was selected on 16 June 1936, approval being given for production of 77 fighters against a contract confirmed early in 1937, with the designation P-35.

Repowered with a P&W R-1830B as the SEV-S1, and with a new tail and cowling, NX18Y raced at the 1935 Nationals, piloted by Frank Sinclair) to fourth place.

It was scrapped in 1937.

Seversky SEV-2XP

TerryLeave a comment

The SEV-2XP (the designation indicating 2-seat experimental Pursuit) designed by Alexander Kartveli was a derivative of the first product of the Seversky Aircraft Corporation, the commercial SEV-3 three-seat monoplane.

An all-metal semi-monocoque aircraft with a fixed spatted undercarriage, the SEV-2XP NX18Y c/n 2 was flown in May 1935 by pioted by de Seversky with the unsatisfactory Wright R-1670 14-cylinder radial offering 735hp for take-off. Provision was made for an armament of two synchronised machine guns, one of 7.62mm and the other of 12.7mm, and one 7.62mm gun on a flexible mount in the rear cockpit.

The USAAC Material Division initiated a contest for a new single-seat fighter. Maj Alexander P de Seversky, believing the SEV-2XP capable of out-performing any single-seat fighter, entered this aircraft as a contender. In the event, the SEV-2XP was damaged in an accident on 18 June while en route to the contest. It was then returned to the manufacturer and reworked as the single-seat SEV-1XP.
