Title: 
Propeller Research Tunnel - Vought VE-7
Description: 
Propeller Research Tunnel balance. Vought VE-7 airplane - set-up and balance details. Fred Weick and Donald Wood wrote in NACA TR No. 300: "The fixed knife edges on the bell cranks are seated on blocks bolted to a rectangular steel frame rigidly fastened to the floor. In addition, this frame is provided with knife edges, links, and counterweights which hold the triangular frame in a fixed lateral position. Screws are also provide for raising the triangular frame from the knife edges while working on the attached apparatus. A stairway at the rear and a grating floor facilitate work on the supports and apparatus mounted on the balance. At each corner of the triangular frame are ball ended steel tubes, adjustable in length and angle, which support the body under test. The forward tubes, in the case of a fuselage with landing gear, have a fitting at the upper end which clamps the axle of the landing gear. The rear post has a ball-and-socket attachment to the fuselage.
