Abstract
Disclosure is directed to an apparatus for expelling liquid fuel from a tank in a rocket engine comprising a flexible bladder which closely fits the walls of the tank and is bonded thereto by an adhesive with a force greater than the force required to flex the bladder to progressively peel the bladder from the tank wall as it is flexed and rolled by a motive fluid to displace the liquid therefrom.
Claims6
In an apparatus for storing and delivering a fluid, the combination of a tank for storing the fluid and having inlet and outlet ports at opposite sides thereof, a flexible bladder attached to the tank between the inlet and outlet ports and of an area to closely fit the wall of said tank, said flexible bladder being movable by a pressure fluid supplied through the inlet from a position where it conforms with one side of the tank to a position where it conforms with the other side of the tank to eject fluid from the tank, and a bonding material adhesively bonding the bladder to the tank wall with a force greater than the force required to flex the bladder whereby to progressively peel the bladder from the tank wall as the bladder is flexed.
An expulsion device comprising:
- a container, inlet means for introduction of a first fluid into said container, an outlet for expulsion of a second fluid from said container, a thin metal diaphragm separating said first and second fluids, said diaphragm being bonded over substantially its entire surface to the interior of said container, whereby said diaphragm will peel from said container smoothly when said second fluid is expelled through said outlet in response to said first fluid being introduced into said container.
