O-2A Aircraft Sea Flight Loads Recording Program
Abstract
Between June 1970 and January 1971 twenty-one O-2A aircraft operating from DaNang and Bien Hoa Air Bases, Republic of Viet Nam, were each equipped with either a VGH or a multichannel recording system to establish maneuver and gust loads spectra for the O-2A aircraft operating under combat conditions. Of the 2053 hours of valid data documented in this report, all represent VGH data (airspeed, altitude, and c.g. vertical acceleration) and 708 represent multichannel data (the foregoing parameters plus pitch and roll angular rates). The data presentation includes tables and graphs of the parameters in the form of histograms, exceedance plots, and bivariate and trivariate tables. The tables list the number of parameter peaks occurring in the ranges of the given parameter and the coincident ranges of other parameters and the time spent in the coincident ranges of several parameters. Data recorded during store drops were processed separately to reflect aircraft operation during weapon deliveries. Of the 428 rocket passes recorded, 272 had acceleration peaks between 2.0g and 3.0g and only 27 had peaks over 3.5g. The instrumented aircraft, on the average, exceeded the maneuver load factor of 4.0 every 300 hours.
