Zusammenfassung:
The Fire Scout helicopter is the Vertical takeoff and landing Tactical Unmanned Aerial Vehicle (VTUAV). The Fire Scout is planned to be operated from USN FFG-7 frigates, Littoral Combat Ships (LCS), and land-based shelters. Prior to induction of the Fire Scout into service, a realistic usage spectrum is required to assess dynamic component fatigue lives. Ten broad mission profiles with various durations were used to develop a fatigue usage spectrum. It is assumed that 90% of missions will be conducted aboard ship and 10% from the land. The limits of Nz, velocity, altitude, and Angle of Bank (AOB) were established from V-n, V-h, and AOB-V envelopes. Each mission is composed of takeoff, hover, climb, level fight, maneuver, descent, and landing segments. Velocity, AOB, Nz, and torque levels were assigned to each maneuver occurrence in the mission profile. Maneuver duration and occurrences were computed for all maneuvers in each mission profile. Rotor start and stop, landings, and Ground-Air-Ground (GAG) cycles were established using recorded Anti-Submarine Warfare (ASW) mission data from various U.S. Navy helicopters. In this manner, the conservative fatigue usage spectrum was developed to calculate fatigue lives of VTUAV dynamic components and to determine service life.
