2、ORD A group of knowledgeable specialists were called upon to provide a useful guide in preparing a specification for design of Aerospace Ground Equipment used in conjunction with space vehicle systems. The following information report is based on their experience in the equipment and operations area
3、s. As more data becomes available and state-of-the-art launch operations advance, it is the intention of this Committee to continue to pursue this area to update these re- commendations. The Committee recognizes that an all inclusive approach for the en- tire spectrum of the space vehicle field is n
4、ot possible. These data and information are to be identified with unmanned space vehicles and boosters of the Thor, Atlas, and Titan class. The recommended performance and system requirements are intended as typical or re- presentative within the scope of this document. $- Printed in U.S.A. Copyrigh

INTRODUCTION 1.1 Intended Use:
21、 This specification is intended to define design requirements and test procedures (1) to be followed in subjecting Aerospace Ground Equipment (AGE) for space systems to simulated and accelerate environmental conditions that will insure satisfactory operation and (2) to be followed in reducing deteri
22、- oration when AGE is operated and/or stored at manufacturing facilities, test facilities, and launch ranges. 2. SCOPE 2.1 Scope: This specification establishes environmental criteria for designing Aerospace Ground Equipment (AGE) in support of space systems. The test levels in this specification ha
23、ve been elevated to compen- sate for absence of combined environments during test, and to allow for variations in equipment and operating conditions. Environmental requirements are summarized in Table 1. 2.2 Classification of Environments: Environments identified in this specification are defined in
24、 section 3. (Definitions) and classified as follows: (a) Transportation, Handling, and Storage Environments (Nonoperating) (1) Controlled (2) Uncontrolled (b) Sheltered Environments (Operating) (1) Controlled (2) Uncontrolled (e) Unsheltered Environments (%mating) (1) Unexposed to Booster Blast (2)
25、Exposed to Booster Blast (d) Semisheltered Environments (Operating) (i) Sheltered and Uncontrolled (2) Unsheltered 3. DEFINITIONS 3.1 Equipment: Equipment is the general nomenclature used to describe parts: components, subsystems, or systems. Requirements and procedures stated herein shall be applic
26、able to equipment purchased or manufactured for use as Aerospace Ground muipment (AGE) for Space Systems and set forth in the in- dividual equipment specification. 3.2 Individual Equipment Specification: Reference herein is related to detail design specifications and appli- cable drawings for the in
27、dividual equipment. 3.3 Detail Design Specification: A detail design specification is defined as criteria for design requirements, physical properties and test requirements of equipment. 3.4 Environments: For the purpose of this specification, environments are defined as follows: 3.4.1 Transportatio
28、n, Handlinp. and Storage Environments: This class of environment refers to packaged anc unpackaged AGE; when in transit (shipping), handling during transfer (packaging, shipping, receiving, storing, and installation) and storage (awaiting installation and not in use). During these periods AGE is not
29、 operable and relegated to shipping containers, storage containers, packages, crates, wrappers, and covers, where applicable. AGE in this category will subsequently be unpackaged and operated in one of two types of environments - controlled or uncontrolled. SAE AIR*LLb7 70 8357340 0003b06 2 -2 - 3.4
30、.1.1 Controlled Ehvironment: handling, and storage considerations dictated by the sensitive and delicate nature of the equipment. Typical examples of locations where this type of environment exists are manufacturing (factory) areas, a Vehicle Systems Test area, a Missile Assembly Building, a Launch
31、Operations Building, a Launch Service Building, and other buildings and trailers in which the environment is controlled by installed conditioning equipment provided at the site. AGE is exposed to this class of environment due to special transportation, 3.4.1.2 Uncontrolled Environment: An uncontroll
32、ed environment is identified with the lack of any control of induced and natural environments in which the equipment is to be handled, operated, or stored. Equipment used in an uncontrolled environment is designed to withstand adverse conditions. Uncon- trolled environment includes areas outside of
33、buildings and trailers. 3.4.2 Sheltered Environments: AGE exposed to this class of environment is located within an enclosed structure. The equipment is secured and operable or on stand-by status. AGE in this category func- tions in one of two types of environments - controlled or uncontrolled. 3.4.
34、2.1 Controlled Environment: AGE identified with this type of environment is protected against natural and induced environment extremes, including provisions for concurrent monitoring, control and adjustment. Typical examples of locations where this type of environment applies is referred to in 3.4.1
35、.1. 3.4.2.2 Uncontrolled Environment: AGE identified with this type of environment is capable of withstanding natural and induced environment, and excludes the need for functional attention, except for adjustmer and replacement. Typical examples of locations where this type of environment exists inc
36、lude in- teriors of launch pad buildings, other out-buildings, trailers, vehicle shelters, and gantry shelters where no attempt is made to control the environment. 3.4.3 Unsheltered Environments: This environment includes operating or stand-by AGE which is completely unprotected against the extremes
37、 of natural and induced environments. AGE in this category will be exposed to two types of environments - unexposed and exposed to booster blast. 3.4.3.1 Unexposed to Booster Blast Environment: AGE identified with this type of environment is of rugged construction and has built-in capability for res
38、isting environmental extremes. Typical examples of this environment are stated in 3.4.2.2. 3.4.3.2 Exposed to Booster Blast Environment: AGE identified with this type of environment is located in close proximity of the vehicle and booster. This type of environment is confined to the launch pad, gant
39、ry, and mast areas due to the influence of booster operation. 3.4.4 Semi-sheltered Environments: This environment includes AGE which is exposed when secured and operating under a protecting cover. The environments as identified in 3.4.1.2 and 3.4.3 may range between in part application to not applic
40、able. cover for the purpose of reducing exposure of AGE to rain and direct (overhead) sunlight. Sand and dust, salt fog, driven rain or low (morning/afternoon) sun are not applicable to the above. A curtain which encloses the AGE, in addition to a roof, is considered adequate to eliminate the effect
41、s of driven rain and low sun. section 4. Semi-sheltered structures may consist of a roof or Consideration must be given to each installation and the particular environments of (Environmental Requirements) to which it will be exposed. 4.
