FEBRUARY 14, 1935. FLIGHT. 179 •itv duties—the new Grumman XJF-i amphibian three seater. Its |hp "Twin Wasp " R-1830-62, gives a top speed of 197 m.p.h. [\VY AIRCRAFT is awaiting the final outcome of choice with the others. These include the Vought X05U-1 and the Berliner-Joyce X0J-3. The former is similar to the others on test, while the Berliner- Joyce is an amphibian. Bellanca has delivered a scouting type, the XSE-2, which is a two- seater high-wing monoplane. In this machine the rear of the cabin is cut away to allow the gunner a clear field of fire. Originally it was produced as the XSE-i, but a crash at the factory hampered its delivery. It was, how ever, rebuilt with numerous changes, and from all indications is very much of a scrapper. It is believed to be powered with a Pratt and Whitney " Hornet " of about 700 h.p. A Vought model, the XSBU-i scout- bomber, has also been delivered. It is typical of the Vought types now in service, being a two-seater biplane. With a drastic change of design for a naval bombing aeroplane, the Consolidated concern have produced their XBY-i. This is an all-metal adaptation of their stock model commercial " Fleetster " monoplane, and is a two- seater. The machine has proved itself to be very sturdy for normal bombing and has a high speed, the power plant being a " Hornet " giving about 700 h.p.

Torpedoplane BY AN AMERICAN CORRESPONDENT The Douglas Company recently delivered their XT3D-2, a four-seater torpedo-bomber biplane, comparable with the British T.S.R.s, and powered with a Pratt and Whitney " Twin-Wasp " SR-1830-C of 850 h.p. The crew sits in tandem and are enclosed by a sliding transparent cover. It was built for carrier duty, and, most likely, will replace some of the older models now in service. Douglas also has in progress the XP3D-1, a monoplane flying boat of the patrol class. It has been reported that this will appear with two Pratt and Whitney engines. Rumours have it that both Douglas and Northrop are interested in building a high-speed torpedoplane. The specifications called for in this type require a speed of at least 200 miles an hour. In the large patrol flying boat types Consolidated is fur nishing additional machines of the P2Y-1 class. With a few modifications, they will be identical with those comprising Of rather " British bein lted X^-i (575 h.p. -Hornet «on of the commercial " " B-i), is an all-metal adapta-Fleetster." appearance—the Douglas four - seater torpedo - bomoer (850 h.p. "Twin Wasp " SR 1830-C). the squadron which last year flew from California to Hawaii for a change of station. A large number of them are under construction to replace some older types now in service. They are powered with two 700 h.p. Wright " Cyclones " mounted on their monoplane wings. They have a top speed of 142 m.p.h., and can cruise at 115 miles an hour for 3,000 miles. Dimensions are: Span, 100ft. ; length, 61ft. gin. ; height, 17ft. 3m. ; wing area, 1,513 sq. ft. The hull construction is of aluminium alloy, and a crew of five is carried. Recently adopted for service was an interesting utility amphibian known as the Grumman XJF-i. It is a three- seater, powered by the Pratt and Whitney " Twin-Wasp " R-1830-62 of about 800 h.p., which gives it a speed of ig7 m.p.h. The crew may be enclosed by the sliding cockpit cover, and the wheels fold up into the sides of the fuselage. The machine as a whole is very similar to the older Loening amphibians, and this may be attributed to the fact that Mr. Grumman was previously one of the Loening engineers who was responsible for the original design. Like the Army Air Corps, the Navy felt the need of fast transport machines to carry personnel and supplies. The most recent adoption in this case has been the Douglas R2D-1, which is none other than the famous DC-2 air-liner. Many machines of the Douglas RD-3 "Dolphin " class (amphibian-transport type) are in service. They are of monoplane design and powered with two Pratt and Whit- nev Wasp 450 h.p. engines. The cabin contains seven seats in two rows. The Bellanca XRE-2 is also undergoing tests as a trans port. It has the appearance of the well-known commercial type, and has a 550 h.p. Pratt and Whitney engine.
