Groff, Randolph B Patrick U. Tactical requirements may include carrying and handling materiel over various types of terrain, negotiating obstacles, immersion in various depths of water, and exposure to dust and sand laden atmospheres, which are likely to result in contamination and ingress of foreign substances including non-pure water.
For the purpose of this leaflet, materiel includes items that may be packaged or unpackaged, or materiel contained within some form of battlefield container.
Such conditioning is particularly applicable to materiel installed on vehicles deployed in open spaces in wet tropical regions of the world. Overloading performance of cooling systems resulting in: Severities of concentration and distribution of particulates are generally less than those experienced in open sky situations. High altitude aircraft and missiles Road and rail transportation 2.
As systems warm up, conditions will tend to stabilise and levels of RH will probably decrease with heat dissipated aecgp operational equipment. Latest News of the Blog. Pressure Pressure sensitive devices designed to detect and respond to small changes in pressure may incur permanent damage during air carriage in cargo bays of transport aircraft. Aircraft compartments may be pressurised to limit and maintain compartment atmosphere at acceptable pressures equivalent to a nominal altitude above sea level.
Rapid change of temperature Dust and sand Operation and movement of common carriers are likely to generate aect; of dust and sand that penetrate inside light closed covers because they are not dustproof. Data on induced temperatures should be derived from measurements made at the intended location of materiel on the flight platform during representative worst-case conditions.
Dimensional changes and differential thermal contraction of structural mechanical components causing: Dust deposits inside materiel may cause short-circuiting of insulators, tracking and build-up of static electricity, interference between moving parts, and contamination of lubrication systems.
AECTP – What does AECTP stand for? The Free Dictionary
Immersion and spray a. Zectp and colour industries Consequently, dependent on the insulation of materials used in their construction and the presence or otherwise of heat-dissipating equipment, temperatures in the enclosed areas may be lower than the external ambient during the low temperature part of a diurnal cycle. If materiel is mounted at low positions on the aircraft e. Humidity in Partially and Non-conditioned Compartments The ambient conditions in partially and non-conditioned compartments aedtp range from a dry heat to a damp heat environment.
Operational aaectp of rotary winged aircraft preclude the need for pressurised compartments. Rates of change experienced by carried materiel depend on aircraft performance, the flight or mission profile and whether the materiel is carried in a pressurised or non-pressurised area or container. AECTP does not address all environments arising from accident, hostile conditions or nuclear effects.
Indeed, long-term ground running without forced-air cooling should be avoided in hot, dry regions, otherwise permanent damage or degraded reliability is likely to occur. Materiel mounted on external faces and inside compartments of military vehicles are liable to be subject to mechanically generated dust and sand-laden atmospheres. The absolute aectl experienced by materiel contained within the compartment aect be assumed to be the maximum value of ambient pressure likely to occur at sea, in the order of mbarplus some specified level of overpressure determined to be appropriate.
ENTESC was able to design from scratch, develop, implement, test, qualify and deliver these items in less than 4 months of starting work. The cooling efficiency of materiel located in partially or non-conditioned compartments may be affected by lower density air at flight altitude and may cause operating temperatures to rise to unacceptable levels.
Mining and minerals Erosion by impact See paragraph 2. This aspect is covered actp in these leaflets. Swelling and general deterioration of materials due to absorption xectp water causing: Similar effects are likely to occur inside temporary buildings and ad hoc improvised structures that may be employed in the battlefield.
Aircraft compartments may be pressurised to limit and maintain the atmosphere at an acceptable pressure equivalent to a nominal altitude above sea level, e. Normally during flight, materiel installed in pressurised compartments will experience air pressures ranging between local ground ambient and some lower value equivalent to that at a predetermined altitude, say m.
The latter may be particularly significant for those types of helicopters for which a comparatively large area of the skin of the cockpit is transparent. aecgp
