3.2 A design team is conducting a trade study of recovery options for a rocket-launched high-speed battlefield reconnaissance system. The mission radius is 400 n miles with 1-h time on station. The jet pro- pulsion system used after initial launch has a T/W of 5, and a TSFC of 1.2 lb/lb-hr. The UA T/W without the rocket is 0.4. The UA has a structural mass fraction of 0.3, 100-lb payload, and 40 lb of all other fixed weights combined. The recurring production cost of the UA is $2,000 per pound of takeoff gross weight. The L/D for loiter is 10, and the L/D for cruise is 8. The UA cruises at 300 kt. The two landing-gear options are 1) a destructive recovery without landing gear that has no weight penalty and 2) a retractable landing gear with a mass fraction of 4%. What is the most cost- effective recovery option for five sorties?
