This invention discloses a dual-component thrust attitude control engine, comprising a mounting plate, a swirling mixer, an igniter, and a combustion chamber nozzle. The mounting plate contains two isolated gas chambers, each with an intake pipe connected to its inlet and an on / off controllable solenoid valve at its outlet. The two inlets of the swirling mixture are connected to the outlets of the two gas chambers, and the outlet of the swirling mixer is connected to the inlet of the combustion chamber nozzle. The swirling mixer is used to swirl and mix the gas input into it before outputting it. The igniter is used to ignite the mixed gas input into the combustion chamber nozzle. The combustion chamber nozzle is used to supply the combusted mixed gas for combustion output. This configuration solves the problem that existing technologies cannot simultaneously achieve compact structure, high mixing efficiency, and excellent thermal management performance.

The invention belongs to the field of plant genetic engineering, and provides application of alfalfa cFBP protein in regulation and control of plant types, and the nucleotide sequence of an alfalfa cFBP protein coding gene is SEQ ID NO.1 or SEQ ID NO.3. The invention further provides a preparation method of the alfalfa cFBP protein. The alfalfa cFBP protein coding gene can positively regulate and control the plant height, the branch number and the biomass of alfalfa, and the plant height, the branch number and the biomass of the plant after overexpression of the MscFBP gene are remarkably improved compared with those of a control material. According to the invention, the MscFBP gene is overexpressed through a genetic engineering technology, so that the transgenic alfalfa with remarkably improved biological yield is successfully obtained, and important normal forms and gene resources are provided for cultivating high-yield plant varieties.
