This utility model discloses a real-time detection device for the turbojet power of a vertical takeoff and landing vehicle, relating to the technical field of detection devices. The real-time detection device uses a fixed frame connected to a clamp via a guide rail and a slider structure to fix the turbojet engine. The clamp is connected to the fixed frame via a force gauge set on the axis of the turbojet engine. It can collect thrust data in real time, avoiding the data delay and distortion problems caused by response lag and indirect calculation in traditional dynamometer methods, and significantly improving the dynamic response capability and data accuracy of the detection.

The embodiment of the invention discloses a wind power joint real-time simulation system and method based on Bladed + RTDS and a storage medium. A wind power joint real-time simulation system based on Bladed + RTDS, and the system comprises a GTNET board card which receives a wind wheel rotating speed data signal outputted by a Bladed unit, and a wind wheel torque data signal and a pitch angle instruction data signal outputted by an RTDS unit; transmitting the wind wheel rotating speed data signal to the RTDS unit according to a real-time network communication protocol; the wind wheel torque data signal is transmitted to the Bladed unit according to the real-time network communication protocol; and transmitting the pitch angle instruction data signal to the Bladed unit according to the real-time network communication protocol. The GTNET board card is used as a data interaction medium between the Bladed unit and the RTDS unit, so that the problems of data delay and harmonic disturbance caused by data conversion through level quantity between the communication PLC and the RTDS unit can be effectively avoided.
