Fuselage 1a described in embodiment one, front wing 3a, rear wing 8a, lift fan and angle of rake compound mode can be constituted
Modified model level of approximation rotate propeller wing flap lift-rising connect wing aircraft, with the fuselage 1a described in embodiment two, front wing 3a, after
The modified model level of approximation that wing 8a, lift fan and angle of rake compound mode can be constituted rotates propeller wing flap lift-rising and connects
Wing aircraft, and fuselage 1b described in embodiment three, front wing 3b, rear wing 8b, lift fan and angle of rake compound mode institute energy
The work process that the modified model level of approximation constituted rotates propeller wing flap lift-rising connection wing aircraft is essentially identical, below to implement
The modified model approximation water that fuselage 1a, front wing 3a, rear wing 8a, lift fan and angle of rake compound mode described in example one can be constituted
As a example by propeller wing flap lift-rising connection wing aircraft is moved in flat turn, describe modified model level of approximation in detail and rotate propeller wing flap lift-rising even
Connect the work process of wing aircraft.
When modified model level of approximation rotation propeller wing flap lift-rising connection wing aircraft is parked in ground, for low incidence new line appearance
State, when connection wing aircraft needs to take off vertically, is rotated by the level of approximation of shaped form hanger 5a rear end rotating shaft, shaped form hanger
5a and electric ducted fan turn to just orientation to front wing 3a leading edge, now put down the list seam Fowler flap 7a of front wing 3a trailing edge,
Open the cover plate 13a and hatch door 14a of lift fan of fuselage postmedian, under the elevator 10a of wing 8a wing root trailing edge to the rear, start
Electromotor 16a outside wingtip end plate 15a, electromotor 16a start to run up, and drive generator operation, and electromotor sends electricity
Stream, and drive electric ducted fan to operate together with the electric current of lithium battery group, the fan of the air vent blowout of deformation duct 4a is sliding
Stream flows through front wing 3a top airfoil, and owing to Coanda effect blows out along lower inclined list seam Fowler flap 7a to the back lower place, produces upwards
Lift, simultaneously lift fan due to driven by power blowout slip-stream produce direct lift, lift fan slip-stream can pull gas around
Stream flows downward, and makes the rear wing 8a wing root of lowered elevator 10a produce lift, and the thrust of this power and lift fan is combined in one
Rise, with the lift of front wing 3a before and after trim, and exceed and connect gravity suffered by wing aircraft, make connection wing aircraft take off vertically；
