This disclosure relates to a fuselage shell of a drone and the drone itself. The fuselage shell includes a housing for enclosing a space for accommodating internal components of the drone. The housing includes a bottom wall and a front end wall, a transition wall, and a main body wall sequentially disposed on the bottom wall from front to back along the drone's longitudinal direction. The orthographic projection area of ​​the front end wall along the longitudinal direction is a first projection area. The orthographic projection area of ​​the area enclosed by a first connecting line at the junction of the transition wall and the main body wall and the bottom wall along the longitudinal direction is a second projection area. The first projection area is completely located within the second projection area. The transition wall is a continuous, smooth curved surface extending rearward from the front end wall. This technical solution optimizes the shape of the housing, making it more rounded, suitable for guiding airflow during flight, reducing fuselage drag, and increasing the drone's range.

The application relates to the technical field of aircraft design, and discloses a cooperative control method and system for multi-mode flight of an aircraft and the aircraft. The method comprises the following steps: S1. a cruising efficiency optimization step: in a cruising flight mode, current Mach number, an angle of attack and real-time pressure distribution data from a pressure sensor array arranged at the rear of the upper surface of a main wing of the aircraft are acquired; based on the Mach number and the angle of attack, a target pressure distribution feature under the current working condition is solved in real time through a pre-stored optimization model; the working parameters of a boundary layer management propulsion module integrated in the main wing are dynamically adjusted so that the real-time pressure distribution data approaches the target pressure distribution feature; and S2. a mode conversion cooperation step: in response to a command for conversion to a vertical take-off and landing mode, a preset cooperative conversion sequence is executed. The system-level unification of cruising aerodynamic efficiency and vertical take-off and landing flexibility significantly improves the mode conversion stability and the comprehensive efficiency of the whole task profile.

The invention discloses a lift fan matrix vertical lifting high-altitude rocket launching platform and a using method, and belongs to the technical field of aerospace. The launching platform comprises at least two platform modules, electric ducted lift fans, a battery pack, a rocket docking clamping lock, a high-pressure push rod push-away system, a platform module docking locking mechanism and a flight control system, wherein the platform modules can be separated and docked, and the electric ducted lift fans are installed in the platform modules in a distributed mode. During use, the platform vertically ascends and descends to carry the rocket to a preset high altitude, the rocket is safely separated from the platform in a mode of pushing away first and then separating / descending, and then the rocket is ignited and launched. The electric lift fan matrix is adopted for providing power, the rocket launching platform has the advantages of being high in loading capacity, high in platform stability, capable of being repeatedly used, low in launching cost and the like, and the rocket launching efficiency can be effectively improved.
