November 13th, 1947 AMERICA'S JETS . . . MIXED POWER PLANTS a Inspiringly named Mercator. the Martin XP4M-I Naval patrol bomber has two Pratt and Whitney Wasp Major IB-cylinder four- row piston engines and two General Electric I -40 turbo yets. The maximum speed with all four engines is nearly 400 m.p.h. b An Allis-Chalmers turbo jet (essentially the de Havilland Goblin) supplements the power of the Pratt and Whitney Double Wasp piston engine in the Curtiss XF\ 5C-1 Naval fightt/. c Following the classic Meteor layout, the Curtiss XP-87 night and bad weather fighttr is unusually large for a machine of its class. This size is partially accounted for by a very heavy fuel and armament load. Tne installation of a gun turret has been considered. d Development of the Bell XP-83 long-range escort fighter (two General Electric 1-40$) is believed to have been abandoned. This very heavy type succeeded the original Bell Airacomet. • Tne Ryan XF2R-\ Navy fighter is seen forming wing-tip trails. Like the Consolidated-Vultee XP-SI (f), this tfpe has a General Electric TG-100 airscrew turbine in the nose, Supplementary bower in the Ryan is provided by a 1-16 turbo jet; the XP-81 has an 1-40 for tne same purpose. Both are " all-altitude " fighters.
