Bluntness Can Add Efficiency to Aircraft, Missile

New York—Bluntness can be an aerodynamic asset. Contrary to conventional streamlining concepts and some early supersonic theory, blunt rather than sharp edged wings and rounded rather than pointed bodies may be the most efficient for supersonic and hypersonic flight.

Nuclear Airframe Designers Lose Conventional Load Tools

Los Angeles—Designers of nuclear airframes will lack many of the means by which structural loads of conventional planes are relieved and structural weight is saved, the chief of Lockheed Aircraft’s WS-125A nuclear bomber program told Institute of Aeronautical Sciences members at a recent meeting here.

Air Force Will Switch Drives in B-52

New York—Strategic Air Command reluctance to carry high speed air turbines inside B-52 airframe will result in replacement of present pneumatic alternator drives with Sundstrand hydraulic drives. Starting with airplane number 359, B-52 bombers will be equipped with 40 kva.

Letters

Air-India Training May we please refer you to the issue of AVIATION WEEK of Feb. 25, p. 164? Under the heading India, you have stated that Air-India International pilots and commanders “are still trained by Lockheed and KLM.” We would like to point out that your above statement is incorrect, in that our pilots and commanders are and have been trained by our own Training Organization manned entirely by Indian personnel.

Tighter Traffic Control Rules Proposed for Adoption By Cab

Washington—New air traffic rules designed to tighten traffic control of all aircraft and increase minimum weather conditions for VFR flights have been proposed by the Civil Aeronautics Board for adoption early this fall. The proposed regulations, which will affect eight major functions of the air traffic control system, stem from recommendations submitted to the CAB by military and commercial aviation groups in the latest drive for more positive control of all air traffic.

Jet Flap Effectiveness Doubted

Los Angeles—Boundary layer control and jet flaps have little or nothing to offer the airframe designer who must select engines for maximum cruise efficiency, an audience at the summer session of the Institute of Aeronautical Sciences here was told by William T. Hamilton, staff engineer of Boeing Airplane Co.
