METHOD AND DEVICE FOR DETERMINING POWER THRUST OF MICROSCOPIC ENGINE Russian patent published in 2007 - IPC G01L5/13 G01M15/00 

FIELD: measuring technique.

SUBSTANCE: method comprises setting the micro-engine on one of the plugged ends of the pipe that can rotate in the vertical plane of the lever tube. The micro-engine is oriented so that its nozzle points upward. The lever tube has sectional branch pipe that is made of the side branch pipe rigidly connected with the lever tube and movable branch pipe that is mounted coaxially to the lever tube and can move in the axial direction. The branch pipe is connected with the supply system. The micro-engine is balanced by means of balancing weights. The ring space between branch pipes is set to be minimum by means of the movable branch pipe. The fluid is supplied to the lever tube through the sectional branch pipe and the thrust load of the micro-engine is measures by means of dynamometer that underlies the lever tube. The device comprises movable lever tube plugged from the faces and mounted in stands of the base for permitting rotation. The lever tube is connected with the micro-engine mounted vertically at one of its ends so that its nozzle points upward. The micro-engine has supplying side branch pipe for supplying fluid which is connected with the lever tube and represents the axle for rotation of the lever tube. The device is provided with means for balancing the micro-engine and measuring the thrust. The supplying branch pipe is sectional and has movable branch pipe mounted in pins of the stand for permitting rotation around the axle and rigidly connected with the lever tube and axially movable branch pipe that is connected with the fluid supply system. The means for balancing the micro-engine is made of a movable balancing weight mounted with, e.g., a threaded connection at the other end of the lever tube.

EFFECT: enhanced precision, simplified design, and reduced sizes.
