Specific implementation mode
All features disclosed in this specification or disclosed all methods or in the process the step of, in addition to mutually exclusive
Feature and/or step other than, can combine in any way.
Embodiment one
As depicted in figs. 1 and 2, the integral layout of aircraft be with whole streamlined nearly cylindrical body 1, outside backward
The horizontal tail 3 of the wing 2, control action that are folded inward and vertical fin 4, underwater propeller 5, VTOL device 6 and front end are revolved
The wing 7.
Entire fuselage is divided into nosing and aft body, and entire fuselage is of a straight line type, nosing be suitble to flow with
The airflow design of air-flow, including instrument room and watertight compartment, are used for installing power supply, communication, sensing with the instrument room of water isolation
The air environments such as device, watertight compartment then can absorb water or drain, and complete the dive of complete machine and the operation of floating.After fuselage
Section is connection and the support element of elongated tubular, and inside can be laid with conducting wire and signal wire, and install horizontal tail, vertical fin in tail portion and push away under water
Into device;Fuselage is also equipped with the front end rotor of subsidiary level propulsion.
The breakthrough design for using watertight compartment in this example so that aircraft is realized by the work of watertight compartment
Entire aircraft floating in water and dive, change the pattern that traditional aircraft cannot be freely lifted under water;And lead to
Cross the underwater propeller being arranged in afterbody so that entire aircraft can move ahead under water so that aircraft can be more hidden
What is covered is operated in underwater environment, increases the disadvantage that existing aircraft cannot be hidden.
In the present embodiment, the wing is the thin-walled wing that outside is folded inward backward, is arranged symmetrically in the leading portion of fuselage
The both sides of part rearward are made of for the high mounted wing with the larger upper counterangle the winglet, main wing and wing root that are folded inward,
Equipped with trailing edge flap, entire wing is connected by wing root with fuselage.VTOL device is housed between wing flap and winglet,
It is made of the rotor and horizontal installation part being arranged symmetrically.VTOL device may also function as steady with horizontal tail, vertical fin collaborative work
Determine the effect of posture, horizontal tail is designed with control rudder face with vertical fin.
It hides in order to ensure aircraft repeats in water, water outlet and water, two nacelles of nosing will be used
Seal Design, especially instrument room, it is ensured that the decision of instrument room seals, cannot be because of water inlet so as to cause entire control system
Failure;The design of watertight compartment not only needs the needs for meeting dive and floating, but also copes with hydraulic impact.
Because to realize the vertical operation upgraded and dive under water of aircraft in this example, main wing and machine in vertical lift device
Body is provided with the larger upper counterangle, and winglet is using the setting to main wing horizontal position interior folding, so that it is guaranteed that rotor starts
The preceding disengaging water surface, while roll stability being provided, and aerial high low-speed operations are taken into account, reduce water impact load and underwater navigation
Resistance, to realize the conversion of airflight and underwater navigation motion state.
The control system that instrument room in this example can be installed, can be by controlling horizontal tail and the control rudder face on vertical fin, can
It, can be by controlling underwater propeller, VTOL device and front end rotor group to realize the stability of pitching and yaw direction
At hybrid power system so that complete machine has more flexible flying method, and can further increase flight efficiency and energy profit
With rate.
The invention is not limited in specific implementation modes above-mentioned.The present invention, which expands to, any in the present specification to be disclosed
New feature or any new combination, and disclose any new method or process the step of or any new combination.
