Abstract
Aspirators for inflating devices such as (but not limited to) aircraft evacuation slides and rafts are detailed. Housings of the aspirators may be made of wound filaments of composite materials, reducing their weight as compared to conventional metal structures. Such actions as reconfiguring and repositioning jet nozzles within the housings also contribute to enhancing performance of the aspirators.
