Abstract:
A system for testing a propulsor having a first end that can attach to a payload and having a second end at which thrust is generated, said system comprising:a liquid; a platform extending over the liquid; a first support aligned with a force of gravity, said first support coupled on one end thereof to said platform and terminating at another end thereof above the liquid; a second support aligned with the force of gravity and extending from a point above the liquid to a point in the liquid; a load cell coupling said first support to said second support, said load cell measuring tension in said first support and said second support in a direction aligned with the force of gravity; and a bulkhead sealed to the first end of the propulsor and coupled to said second support in the liquid, wherein only said bulkhead and the propulsor are fully submerged in the liquid with the propulsor being suspended in the liquid with the second end thereof aligned with the force of gravity such that the thrust is directed therealong.
