AERODYNAMIC MODEL OF AIRCRAFT WITH AIR-REACTIVE ENGINE FOR MEASURING EXTERNAL RESISTANCE Russian patent published in 2006 - IPC G01M9/08 

FIELD: experimental aerodynamics, possible use for researching characteristics of aircrafts.

SUBSTANCE: device contains holder, holder cowl, flow meter nozzle, positioned on output portion of through channel. Flow meter nozzle, positioned in output portion of through channel contains throttle, made in form of cylinder with a half of rotation ellipsoid connected to it. Throttle is held on component of mechanism for measuring attack and sliding angles, not connected to aerodynamic weights, on the cowl of holder, on which device is held on aerodynamic weights. Held on the throttle are heads of full and static pressures with receiving apertures in vertical plane before the throttle, and also receiver of braking temperature and receivers of static pressure, mounted at output from flow meter nozzle. Heads of full and static pressures and receivers of static pressure are connected to appropriate measuring devices by means of draining pipes.

EFFECT: decreased internal resistance of aerodynamic model and, respectively, increased precision when measuring external resistance of aircraft model at hyper-sound flow speeds.
