Abstract
KNOWLEDGE of loads on major structural parts of an airplane while in flight is needed for complete utilization of the airplane's strength and capabilities. Some in-flight measuring techniques and equipment for reducing the data thus obtained are discussed in this paper.
Instrumentation and calibration of strain gages for measuring in-flight air loads are described in detail. Wing bending-moment measurements obtained on a Navy PV-2 airplane are used to illustrate data reduction procedure.
