This utility model relates to a blade tip jet rotor small-sized thermal power test facilities. In order to reduce the cost of blade tip jet rotor small-sized thermal power principle test research, This utility model chooses turbojet engine (1) used by model plane. Connect one end of L type breather pipe (2) with the fixed end of revolving seal joint (5), the other end of L type breather pipe (2) with the outlet of engine (1); Connect the connector of Y type breather pipe (4) with the revolving end of revolving seal joint, each branch pipe connector arranges a cone spray nozzle (3). when the tail jet flow is passing through L type breather pipe (2) and revolving seal joint (5), it is divided into two flows in the In Y type breather pipe (4) and blow out from taper spray nozzle (3) , and the reacting force generated by jet air drives the Y type breather pipe (4), cone spray nozzle and the revolving end of revolving seal joint (5) rotate at a high speed. This utility model can carry out the blade tip jet rotor small-sized thermal power principle test. has the advantages of cheap cost, low investment and less occupation of land.
