AFSC FLIGHT EVALUATION OF F-100, TYPE III 335-GALLON EXTERNAL FUEL TANK

Abstract

This report presents the results of an evaluation of 335-gallon external fuel tanks for use with the F-100 aircraft. Testing was completed on 18 August 1961. Flutter tests were conducted to qualify the design limit airspeeds with the tanks installed. The specified limits were reached without onset of sustained flutter. Symmetrical and unsymmetrical design load limits were demonstrated with varied fuel loadings. The limit loads were achieved with no signs of tank shifting or damage. Sixteen tanks were dropped to define conditions for safe tank release with outboard stores installed and with Type III pylons outboard. Tank drops with outboard stores were generally unsatisfactory. A safe airspeed-altitude envelope for drops with Type III pylons outboard was defined. A baffle check valve modification, provided to prevent excess forward or aft fuel loading of the tank, was evaluated. The modification increased airspeed and structural limits with the 335-gallon tanks partially full. Design limit airspeed and structural limits were successfully demonstrated with the modified tanks. Performance of the F-100D with the 335-gallon tanks was evaluated and results will be presented in a separate report. The 335-gallon tanks proved satisfactory for operational use with minor exceptions as noted. (Author)
