Problems solved by technology

When the propeller of the existing helicopter is in operation, due to the upward thrust of the airflow, the base of the blade is inclined upwards to the end, so that the elevation angle of the blade part away from the base becomes larger, the thrust is reduced, and the screw is affected. The proper lifting function of pulp should be brought into play

Embodiment Construction

[0019] Further explanation is given below. As shown in the figure, the multifunctional aircraft of the present invention is to be equipped with a pontoon 3 for taking off and landing on the water supply by a support 2 under the helicopter fuselage 1. The pontoon 3 is divided into two equal left and right, and the fuselage 1 and A rotary drive mechanism that can make the buoyant tank turn up and down along the outside of the fuselage is also housed between the supports 2 . The front and rear ends of the floating tank 3 are equipped with a telescopic sub-casing 4 to one side, and the middle part of the floating tank 3 is equipped with a telescopic sub-casing 4 to the other side, and the sub-casings 4 at the front and rear ends of the floating tank 3 are positioned on the buoy. When case 3 is positioned at fuselage 1 top, be positioned at the inboard of buoyant tank 3, the sub-casing 4 of buoyant tank 3 middle part is positioned at the outside of buoyant tank 3 when buoyant tank ...

Abstract

The invention relates to a multifunctional aircraft and its application. In order to make the pontoon for taking off and landing on the water also have the function of an aircraft wing, the pontoon for taking off and landing on the water is installed under the fuselage through a bracket. A rotary drive mechanism that can make the buoyant tank turn up and down along the outer side of the fuselage is also housed between, or a rotary drive mechanism that can make the buoyant tank vertically flipped is housed between the support and the buoyant tank. Its buoyant tank can be used for water take-off and landing, can also be used as a wing, and can also be used as an armor shell to protect the fuselage. Safe landing while under power greatly improves the flight performance of the aircraft, and is more conducive to adapting to complex flight environments and ensuring the safety of the aircraft and crew.

Description

technical field [0001] The invention relates to aircraft manufacturing technology, in particular to a multifunctional aircraft and its application. The buoyant box of the aircraft for water landing also has the function of aircraft wings. Background technique [0002] At present, most aircraft do not have the function of water takeoff and landing. Since water takeoff and landing need to have pontoons or make the lower part of the fuselage into a hull shape, whether it is a pontoon or a hull-shaped fuselage will increase the air resistance in flight. . This is because no matter the hull shape of the pontoon and the lower part of the fuselage, the shape below it is just opposite to that of the aircraft wing. There will be a downward pull. Therefore, this design has a great influence on the flight speed and load of the aircraft. When the propeller of the existing helicopter is in operation, due to the upward thrust of the airflow, the base of the blade is inclined upwards to...
