Abstract
A system is provided for testing a propulsor having a first end that can attach to a payload and a second end at which thrust is generated. A bulkhead is sealed to the first end of the propulsor. The bulkhead with the propulsor coupled thereto is suspended vertically by a support that is placed in tension when thrust is generated at the second end of the propulsor. A load cell coupled to the support measures tension therein as a measure of thrust.
