Trimble and Advanced Design
George S. Trimble, IL, new 38-year-old vice-president of Glenn L. Martin Co, heads the organization's Advanced Design Department. Recently created it is concerned with search in pure science, immediate- and far-future designs, and over-the-horizon explorations in aeronautics.
A veteran of 17 years of service with Martin, TrimbIe was graduated from Massachusetts Institute of Technology in 1936, joined company the following year, worked as draftsman for three years. From 1940 to 1943 he was in aerodynamics, then spent a year in New Design From 1944 to 1946 he was engaged in propulsion research, then returned for another year in new design work.
From 1947 to 1951 he was chief of Aerodynamics (originally named Fluid Dynamics) then became head of Design Development, a department initiated in 1951. In August, this year, he was made a vice president, with Advanced Design his personal responsibility.
He is a member of the subcommittee on highspeed aerodynamics for the National Advisory Committee for Aeronautics, and a member of Tau Beta Pi, national honorary engineering fraternity.
Plane model shown above with Trimble is a night intruder configuration, one of many designs investigated in studies of advanced planes for possible tactical Air Force application. The jet engine air inlet ducting is not part of wing root but is located under wing so that the latter has a continuous structure for maximum strength and thinness. Broad wing fairing at rear houses landing gear and considerable equipment requiring air. Pointing aft atop the rear of the fairing1s fixed armament.
The horizontal tail is placed sufficiently aft to afford the required stability. then connected by a sharply swept fin to the fuselage. This scheme allows the shortest possible fuselage to be used, to cut down on structural weight. To sight aft, there is a radar high on the tail.
