MIL-E-18927E

Abstract

This specification establishes the general requirements for design and performance of aircraft Environmental Control Systems (ECS) required for occupied spaces and equipment. It includes pressurization, heating, cooling, ventilating, mositure control, bleed air system, ram air supply, pressure and anti-G suit systems, defogging, defrosting, anti-icing, rain removal, electronic/electrical equipment environment, boundary layer control and related systems. <strong>Beneficial comments (recommendations, additions, deletions) and any pertinent data which may be of use in improving this document should be addressed to: Commanding Officer, Naval Air Engineering Center, Engineering Specifications and Standards Department (ESSD), (Code 93), Lakehurst, NJ 08733 by using the self-addressed Standardization Document Improvement Proposal (DD Form 1426) appearing at the end of this document or by letter.</strong> <b><u>Intended Use:</u></b> The requirements of this specification are intended for use in designing environmental control systems for pressurized and unpressurized aircraft for the occupied spaces, electronic and electrical equipment compartments, and various related systems installed in military aircraft. These requirements apply to the ducting, thermal controls, ventilation controls, pressure regulators, and ancillary items of equipment required for related systems such as pressure/exposure suit ventilating systems, external bleed air rain removal, boundary layer control, fuel transfer, photographic systems, etc., using compressor bleed air supply. <br>
