SAFETY

Turbulence Blamed in Viscount Breakup

About 1613, May 12, 1959, Capital Airlines Flight 75 disintegrated in flight over an area near Chase, Md. All occupants, four crew and 27 passengers, were killed. The aircraft, a Vickers-Armstrongs Viscount, N 7463, was destroyed. From all of the available evidence the Board believes that the in-flight disintegration was caused by aerodynamic loads imposed on the aircraft which exceeded its design strength and which were generated by an excessive airspeed combined with turbulence and maneuvering loads (AW Nov. 2, p. 30).

Solids Make Bid for Space Booster Role

Washington—Solid propellant rocket producers are making their first serious bid to move into the million-lb.-thrust-plus class and take on major space booster applications. From information gathered at the 14th annual meeting of the American Rocket Society here last week, the major impetus behind this move appears to be the re-activation of the Air Force requirement for a million-lb.-thrust solid propellant rocket at a bidders conference two weeks ago.

Turbojet Cl-41 Covers Full Training Span

Montreal—First design details of Canadair’s new side-by-side CL-41 jet trainer point to a rugged, flexible airplane capable of covering the full span of student training—from primary through advanced instruction—at speeds ranging from 65 kt. (stall) to 500 kt. or Mach .8 (limit dive).

Rocketdyne Studies Pumps, Future Liquid Propellants

Canoga Park, Calif.—Greater simplicity, rapidly improving turbopumps and signs that better analytical techniques may soon reduce the expense of cut-and-try development are leading trends in liquid propellant rocketry noted at Rocketdyne Division of North American Aviation as second generation development gathers momentum.

Aerocar Makes Quick Airplane Transition

Teterboro, N. J.—Aerocar, the flying automobile, is ready to take to the air (and/or the road) after an 11-year gestation period. The two-place vehicle, designed for the man who wants to drive to the airport, fly to another and drive to his ultimate destination all in the same conveyance, will be produced in 1960 if present licensing negotiations are successful.

EQUIPMENT

Unit Converts Waste Rocket Heat to Power

Princeton, N. J.—Radio Corp. of America and Thiokol Chemical Corp. have developed a new thermionic auxilian power unit which converts the waste heat from a rocket exhaust directly into electricity. Initial units will be designed to fit around the flame tube or into the expansion cone of large solid propellant missiles such as the Eagle, Subroc, Polaris or Minuteman.

Faa Expands Radar Beacon Network

Atlantic City, N. J.—Federal Aviation Agency plans almost complete coverage of the United States by ground installations for its air traffic control radar beacon program within the next 24 months, and complete coverage by 1964, according to a report presented to the Radio Technical Commission for Aeronautics at its annual fall assembly by L. E. Shoemaker, head of the Beacon System Section of FAA’s Development Division.

Radio’s Blackout During Re-entry Probed

Washington—General Electric and Avco scientists seeking to eliminate the blackout of radio communications between ground stations and space vehicles or missile nose cones during atmosphere re-entry are exploring new telemetry radio frequencies at opposite ends of the spectrum, it was reported here during the American Rocket Society meeting.
