The invention discloses a rotary combustion device with shaft work and thrust coupled output. The rotary combustion device comprises a front-end hollow shaft, an inclined spray pipe, a quick-insertion type ignition electric nozzle, a combustion chamber and a rear-end hollow shaft. The front-end hollow shaft and the rear-end hollow shaft are located at the two ends of the combustion chamber correspondingly, and the front-end hollow shaft, the rear-end hollow shaft and the combustion chamber are coaxial. One end of the front-end hollow shaft extends into the combustion chamber, a plurality of nozzles are evenly formed in the circumferential direction of the section, extending into the combustion chamber, of the front-end hollow shaft, and a baffle for blocking an inner cavity of the front-end hollow shaft is arranged at the tail end, extending into the combustion chamber, of the front-end hollow shaft. The front-end hollow shaft is used for introducing fuel oil, and the rear-end hollow shaft is used for introducing air; the inclined spray pipes are mounted on the periphery of the combustion chamber and are uniformly distributed; and the quick-plug ignition electric nozzle is also fixedly connected to the periphery of the combustion chamber. The engine is high in working reliability, high in combustion efficiency and light in weight, and thrust and rotating torque of different magnitudes can be adjusted to be output.

This invention provides an asymmetrical tilting duct, belonging to the field of aircraft technology, including a duct shell. The duct shell is a non-closed arc structure along the circumferential direction, and the duct shell has a non-closed opening section on its circumference. The cross-section of the opening section is an airfoil with inverted upper and lower arcs. By designing the duct shell as a non-closed arc structure and setting a non-closed opening section with an inverted airfoil cross-section on its circumference, this invention breaks the symmetrical distribution of circumferential air pressure in the duct, forming a circumferential pressure difference that cannot be completely offset. This allows the duct to generate additional radial lift along the vertical direction of the fuselage while providing axial thrust, effectively offsetting part of the wing load and improving the aircraft's payload ratio.

The present invention belongs to the technical field of molten salt heat storage in thermal power plants, and specifically discloses a reheat steam staged regulation power station deep peak regulation heat storage and release system and method. Based on the use of reheat steam to heat low-temperature molten salt, the present invention adds electric heating, extracts air from the reheat steam to exchange heat with the molten salt, and adopts electric heating and molten salt heat exchange staged to improve the stability of the system, the flexibility of heat storage and the efficiency of heat storage. The present invention is suitable for the flexible transformation of thermal power plants.
