In the aerospace context, "aspiration" can refer to the process of drawing in air or other gases, typically through the use of a fan or other mechanical means. Aspiration is often used in the aerospace industry to provide ventilation or cooling to aircraft or spacecraft, and it is an important part of many aerospace systems.
Examples of aerospace applications that might use aspiration include aircraft ventilation and cabin pressurization systems, aircraft engine cooling systems, and spacecraft environmental control systems. Aspiration is an important part of many aerospace systems, and it plays a critical role in maintaining the safety and comfort of passengers and crew and in ensuring the proper operation and performance of aerospace systems.
