Light Helicopter Family Trade-Off Analysis. Volume 10. Appendices V, W, X, and Z
Abstract
This volume of the Light Helicopter Family (LHX) Trade-Off Analysis (TOA) report gives the details of four substudies done within the TOA. These substudy areas were: Safety, Cost, Commonality, and Downwash. The findings/ conclusions reached by the Safety Analysis included: (1) The LHX should be planned for two crewmembers; (2) The LHX should be designed with two engines; (3) These important safety design features should be included in the LHX: (a) twin engines with an OEI flight capability; (b) Effective antitorque control under all mission flight environments; (c) No tail rotor or a high degree of protection for the tail rotor; (d) Visionics system for use during reduced visibility conditions; (e) Wire strike protection system (WSPS); (f) Backup or redundant flight control system; (g) Wheeled landing gear; (h) Rigid or redundant flight control system; (i) Maintenance and flight data recorders; (j) Performance planning computer; (k) Automated systems to reduce pilot workload; (4) The following crashworthiness items are important and should be features of the LHX: (a) Crashworthy fuel systems; (b) High mass item retention; (c) High- energy absorption gear (fixed or automatic extension) and fuselage; (d) Crew seat and restraint system; (e) Troop seat and restraint system; (f) Noninjurious cockpit environment; (g) Emergency locator transmitter (ELT).
