Environmental Control Systems (ECS) for UA (Unmanned Aircraft)

2022-06-24

WIP

AIR7063

This document provides guidance for establishing ECS for UA by primarily referencing existing AC-9 documents that apply with some indication how they need to be adapted. The document primarily addresses cooling requirements for UA equipment. Limited information is provided for ECS requirements for future UA that may carry passengers. The document does not intend to provide detail design guidance for all types of UA. This document only provides guidance related to environmental control of onboard equipment, cargo and possible animals and passengers. It does not pertain to the related ground stations that may be controlling the UA.

HISTORICAL

ARP986B

This Aerospace Recommended Practice (ARP) defines tests to be performed on hydraulically, electrically, pneumatically, and mechanically actuated air valves. They may be further defined as those valves that function in response to externally applied forces or in response to variations in upstream and/or downstream duct air conditions in order to maintain a calibrated duct air condition (e.g., air flow, air pressure, air temperature, air pressure ratio, or air shutoff).

HISTORICAL

ARP986

This document defines the tests to be performed on electrically, pneumatically, and mechanically actuated (regulating, modulating, and shutoff) air valves. The valves may be further defined as those which function in response to externally applied forces or in response to variations in upstream and/or downstream duct air conditions to maintain a calibrated duct air condition (i. e., air flow, air pressure, air temperature, air pressure ratio, etc. ). The requirements of this document should govern for all qualification tests unless different requirements are established by the detail specifications.

AIR1266B

This SAE Aerospace Information Report (AIR) outlines concepts for the design and use of fault isolation equipment that have general application. The specific focus is on fault isolation of environmental control systems (ECS) in commercial transports. Presented are general fault isolation purposes, design principles, and demonstration of compliance criteria. These are followed by three design examples to aid in understanding the design principles. Future trends in built-in-test-equipment (BITE) design are discussed, some of which represent concepts already being implemented on new equipment.
