This invention relates to a low-altitude
spacecraft capable of both amphibious
takeoff and landing, belonging to the field of low-altitude aircraft technology. The invention increases the contact area between the
hull and water by combining a flat
hull bottom with a horizontal
hull section, effectively improving the stability of the
spacecraft during water navigation. Simultaneously, an arc-shaped hull lifting section is incorporated. During
takeoff and as the
spacecraft ascends,
water flow is diverted along the arc structure, creating a dynamic
water pressure difference above and below the hull, generating an upward lifting force to counteract water drag. Combined with the ground effect, this enhances the lift coefficient, helping the hull quickly rise above the water and complete
takeoff. Furthermore, the invention employs a multi-layered, multi-wing
layout structure, which, during operation, can generate a
high lift coefficient through a power superposition effect, producing an excellent thrust-to-weight ratio and ensuring stable flight of the spacecraft.
