The invention discloses a distributed propulsion system test bed for a short-distance/vertical take-off and landing aircraft, and belongs to the field of aviation. The test bed comprises a distributedpropulsion system, a control system, a rack system and a six-component balance force measurement system, wherein the distributed propulsion system adopts a generator coaxial with a turbojet engine asa power source of a lift fan, a ducted fan and a three-bearing exhaust nozzle stepping motor, a power system closed loop without external energy input is achieved, and the actual working state of theshort-distance/vertical take-off and landing distributed propulsion system is truly simulated. All systems in the test bed cooperate with each other, power closed-loop and control rule test researchcan be carried out on distributed propulsion systems of short-distance/vertical take-off and landing aircrafts with different layout requirements, complete thrust data measurement of a short-verticalmode, a level flight mode and a transition state of the propulsion system is realized, and design optimization and control law research requirements of the distributed propulsion system of the short-distance/vertical take-off and landing aircraft are met.
