    Enclosure (1) H-65 Environmental Control System (ECS) Performance Objectives.pdf
    The H-65 Environmental Control System (ECS) Performance Objectives outline the design and operational requirements for an ECS. The system must provide 3 or more tons of cooling with 600 CFM airflow, operating effectively in ambient temperatures up to 103°F/50% RH outside and maintaining 73°F/50% RH inside, while also cooling avionics up to 122°F. Key design details include directing 100 CFM of cooled air to the avionics compartment at a desired 38°F, separate temperature sensors and controls for avionics and cabin, water separation, and low/high temperature protection (38-170°F). The system’s desired weight is 35 lbs (100 lbs maximum), including the cooling unit and controls, and a desired size of 11.5 x 28 x 28 inches. These specifications are critical for the H-65 helicopter's environmental control needs, ensuring both cabin comfort and avionics protection.
    Enclosure (2) H-65 Data.pdf

Crash load design factors for cabin equipment are provided, along with the requirement for all modifications to meet or exceed 14 CFR 29 Airworthiness Standards. The file also details the pulley system for air conditioning compressors. The H-65, a USCG Short Range Recovery helicopter, is designed for search and rescue, capable of various operations day or night, and is NVG compatible. It features a robust fuselage construction, dual flight controls with an AFCS, two turbo shaft engines, a 4-blade main rotor, and a shrouded tail rotor. The helicopter is equipped with dual hydraulic and electrical systems, a CAAS Avionics Management System, FDS, weather/search radar, ECS, emergency flotation, a 2,000-pound cargo hook, and a controllable searchlight. Its maximum unrestricted gross weight is 8,900 pounds, with restricted operations up to 9,480 pounds.
