FLIGHT, 20 July 1950 must suffice. The cabin floor is con- structed of removable honeycomb-sand- wich-type panels forming an integral part of the fuselage structure ; thus the portion below the floor is little more than fairing, allowing the installation of large servicing hatches in the botton skin without the addition of heavy structural reinforce- ments. In this manner, the flight con- trol, hydraulic, electrical and cabin-heater systems, and cockpit instruments, are easily accessible from the ground, elimi- nating the need for mechanics to enter the cabin. As if tp ward off the death-rattle of the piston-engine for as long as possible, Martin's say: " The 4-0-4 will be the first production airliner designed and stressed for conversion to turboprop engines, when such latest type power plants are released by the Military Services for commercial use, expected within three to five years." (Italics are the writer's). The first part of this statement—in so far as American manufacturers are concerned—may be Convair, but it may be true for all that, An artist's impression of the 3-0-4 mode! which was to have been Martin's bid for the first post-war turbopropped airliner, powered with General Electric TG-IOOs. Engine development fizzled out, however, and this particular Martin failed to hatch. The 4-0-4 may be turbopropped later with Allison T-38s. disputed by for it will be recalled that Martin prepared a design study of a turbo- propped transport for United Air Lines in 1946. This was to have been the pressurized 3-0-4 model, designed around the General Electric TG-100 (XT-31) engine, but the scheme fizzled out when the engine development came to a dead- end. As for the wistful pessimism implied by the italics, one is inclined at first to discount such a protracted engine '' bug hunt'' in the light of the recent General Motors- Convair deal with the Allison XT-38 turboprop. Surpris- ingly, however., both Douglas and Lockheed recently issued public statements to much the same effect. Donald Douglas told his stockholders that company engineers had been discussing with the airlines the possibility of turbopropping the DC-6, a conversion which might be expected to increase the cruising speed from 300 to 360-380 m.p.h., while reduc- ing seat-mile costs to 30 cents. " But," said Douglas, " we don't have an acceptable turboprop engine at an acceptable price available now." Moreover, he estimated it might be four years before turbopropped transports are put into commercial operation. Lockheed, too, in announcing an order from Eastern Air Lines for 10 new Super-Connies, with an 18ft longer fuse lage design seating a maximum of no passengers, estimate that it will be three or four years before this new model will be equipped with Allison turboprops. All these dolesome predictions of to-day are completely at variance with yester- day's publicity claims in the American Press on behalf of the Allison XT-38 and XT-40 turboprops. Our own per- sonal feeling is that once the turbopropped Convair-Liner gets around the country on its shakedown tour, things will begin to move at a more typically American tempo. Nonetheless, with a backlog of undelivered orders now running at around $92 million and prospects for additional new commercial contracts promising, the Martin company has pulled out of the financial and technical gloom of the immediate post-war years. A large share of the credit for this resurgence is undoubtedly due to the new and spirited leadership of C. C. Pearson, late of Douglas (who was brought in by the Martin Board for just that purpose), ably assisted on the manufacturing side by our old ex- Gloster colleague Tom Willey—one of the best aircraft engineers who ever left a drawing-board in England to find well-earned promotion to a directors' board in America. Anyway, until such time as the Convair cuckoo comes home to roost, things look cheerful in the Martin's nest. R.Ae.C.
