MONITORING HIGH SPEED FLIGHT

CD 1967082 E&MP129.001

Telemeter

August 29, 1952

Two engineers of the Douglas Aircraft Company Testing Division, J.H. Vaughan (foreground) and S.F. Tydeman, are monitoring a high speed flight from a console of a telemetering trailer stationed on the field.

Vaughan, a power plant expert, is paying special attention to the power output while Tydeman, an aerodynamicist, checks speed.

By flicking various toggle switches, engineers can obtain data from any one or combination of the 176 measuring devices aboard the airplane.

Information they receive permits them to radio instructions for further performance tests to the pilot or caution him to remain within certain safety limits.
