Soft cover. Condizione: Very Good. Lear-Jet Helicopter. Helicopter Program Master Schedule. Learjet, Wichita, Kansas. August 1, 1969. Mimeographed. 11"x 8.5", 9 folding sheets (11"x 17", folded in half). Cover letter plus introduction. The intro is paginated 1-2, and the folding charts seem to be paginated 3-11. No doubt there w…as a report to go with this (?), but as it stands now what I have here is the master schedule for construction of the twinjet helicopter for 1969-1972. This seems a timeline for the construction of the entire helicopter, listing the following categories (subsequent sections) including headings for Engineering (application for test cert, sales mock up, etc., analysis reports, plus 20 units); Manufacturing (25 units); Certification test program (5 units); Rotor Wheel Test Programs (5 units); Static Test Aircraft (5 units); Tie Down Test Aircraft (10 units); Components and Assemblies (fuselage, nose, cabin, tail.); Main Rotor (16 sub-categories); Main Rotor Control; Tail Rotor; Forward Landing Gear; Aft Landing; Power Plant (fuel, oil system, exhaust system, engine mounts, drive shaft); Flight Control (cockpit control assembly, 16 other units); Electrical System (11 units); Avionics (17 units). "The Gales Twinjet helicopter, a twin-turbine ship designed for corporate transportation and utility applications, was 10 years and one recession ahead of its time. Unveiled as a mock-up craft on September 11, 1969, at the Gates LearJet plant in Wichita, Kansas, the pioneering helicopter was to cruise at 180 mph and carry eight to twelve passengers. The project gathered what some called the finest group of experts from throughout the helicopter industry, and drew upon the experience of engineers from Bell, Boeing Vertol, Hughes and Sikorsky. More than $4 million was spent on the project, with more than 100 full-time engineering personnel involved. Preliminary structural details announced in 1969 were for an aircraft that would sell for between $400,000 and $450,000 that could be used for office-to-airport travel. Range would be 400 miles. It was to have a fuselage that would be both aerodynamic and make maximum use of cabin space. It would have a low empty weight and an optimized rotor configuration that would provide the best lift/drag ratio for high performance at a gross weight of 6,000 lbs. The four-bladed main rotor's diameter was 40 feet, and the ship's overall length was 42 feet. Two 474-shp Garrett TSE turboshaft engines were to be mounted above the main cabin in stub wing fairings. The baggage compartment was to be 70 cubic feet. Complete preliminary layouts of all systems had been accomplished, and master tooling and major production facilities were nearly operational when the project was dropped because of the 1970-71 recession. The Gates Twinjet had been scheduled to make its first flight in 1971, with FAA type certification to have been completed in 1972."--Source: ROTOR, Spring 1997.

No Binding. Condizione: Good. LEARJET factory plans in blueprint, ca. 1970. These are two blueprinted factory plans for Learjet ("Lear-jet") in Wichita, Kansas, ca. 1970 (ca. 1968-1971). These are thick-ish sheets of paper, very crisp and freshmeaning that they have very seldom been unfolded. There is discoloration at the fold s…eems, as appears (in my experience) to be normal (or at least not unexpected or surprising) for 50+ year-old blueprints. The non-blue colors on the two sheets are applied by hand. The first sheet is the ground floor of the factor; the second is the plan for the second level. These come with the impressively-engineered file folder from the timeall I can say about this file folder is that THIS is the way to make one of those. [++] Provenance: Harry W. Johnson, VP Engineering, Aircraft Division, Gates Learjet Corp; previously TRW, Lab Manager Systems Group (lunar module descent engines); NASA 1951-1954. [++] Very cool.
