Abstract

A jet aircraft maneuvering characteristic simulation system for a single propeller aircraft includes a power lever, speed brakes, and a controller. The power lever is configured to change a thrust of the single propeller aircraft. The speed brakes are provided on respective right and left sides of the single propeller aircraft. The controller is configured to, in response to an operation of the power lever to raise the thrust of the single propeller aircraft, deploy both the right and the left speed brakes to cause an increase in speed of the single propeller aircraft to be moderate, and control the speed brakes to cause a force in a yaw direction and a force in a roll direction to be generated that act against a turning tendency of the single propeller aircraft by making amounts of the deployment of the right and the left speed brakes different from each other.

First claim

The invention claimed is:

1 . An aircraft maneuvering system for a single propeller aircraft, the aircraft maneuvering system comprising:
a power lever configured to change a thrust of the single propeller aircraft; speed brakes comprising a right speed brake and a left speed brake provided on respective right and left sides of the single propeller aircraft; and a controller configured to, in response to an operation of the power lever to raise the thrust of the single propeller aircraft,
deploy both the right speed brake and the left speed brake to delay an increase in speed of the single propeller aircraft upon the operation of the power lever; and
control the speed brakes to generate a yaw force and a roll force that oppose a turning tendency of the single propeller aircraft, by making an amount of deployment of the right speed brake and an amount of deployment of the left speed brake different from each other.

2 . The aircraft maneuvering system for the single propeller aircraft according to claim 1 , wherein the controller is configured to control the speed brakes to make an amount of the deployment of the right speed brake greater than an amount of the deployment of the left speed brake in a case where the single propeller aircraft has a left-turning tendency, and control the speed brakes to make the amount of the deployment of the left speed brake greater than the amount of the deployment of the right speed brake in a case where the single propeller aircraft has a right-turning tendency.

3 . The aircraft maneuvering system for the single propeller aircraft according to claim 2 , wherein the speed brakes are provided on respective right and left main wings of the single propeller aircraft.

4 . The aircraft maneuvering system for the single propeller aircraft according to claim 3 , wherein the single propeller aircraft comprises a power supply unit configured to serve as the controller.

5 . A single propeller aircraft, comprising the aircraft maneuvering system for the single propeller aircraft according to claim 4 .

6 . A single propeller aircraft, comprising the aircraft maneuvering system for the single propeller aircraft according to claim 3 .

7 . The aircraft maneuvering system for the single propeller aircraft according to claim 2 , wherein the single propeller aircraft comprises a power supply unit configured to serve as the controller.

8 . A single propeller aircraft, comprising the aircraft maneuvering system for the single propeller aircraft according to claim 7 .

9 . A single propeller aircraft, comprising the aircraft maneuvering system for the single propeller aircraft according to claim 2 .

10 . The aircraft maneuvering system for the single propeller aircraft according to claim 1 , wherein the speed brakes are provided on respective right and left main wings of the single propeller aircraft.

11 . The aircraft maneuvering system for the single propeller aircraft according to claim 10 , wherein the single propeller aircraft comprises a power supply unit configured to serve as the controller.

12 . A single propeller aircraft, comprising the aircraft maneuvering system for the single propeller aircraft according to claim 11 .

13 . A single propeller aircraft, comprising the aircraft maneuvering system for the single propeller aircraft according to claim 10 .

14 . The aircraft maneuvering system for the single propeller aircraft according to claim 10 , wherein
respective trailing edges of the right and left main wings have right and left ailerons, and the controller is configured to deploy the right and left speed brakes and thereafter close the right and left speed brakes.

15 . The aircraft maneuvering system for the single propeller aircraft according to claim 1 , wherein the single propeller aircraft comprises a power supply unit configured to serve as the controller.

16 . A single propeller aircraft, comprising the aircraft maneuvering system for the single propeller aircraft according to claim 15 .

17 . A single propeller aircraft, comprising the aircraft maneuvering system for the single propeller aircraft according to claim 1 .
