1. This test instrument can expediently test for gyroplane rotate speed adjusting amplifier. It has certain martial and economic value.

2. The results showed that images from gyroplane exhibited significant geometric distortion, and the precision of the corrected images can satisfy the requirements in precision agriculture.

3. The gyroplane also is different from the airplane. It depends on the rotors to produce lift. It has no fixed wings, or has assistant wings.

4. The Breguet - Richet Quadrotor helicopter Gyroplane No.1 built in 1907 is reported to have lifted into flight.

5. In view of gyroplane rotate speed adjusting amplifier in backward test technique, a method of automatic test gyroplane rotate speed adjusting amplifier by computer test technique is put forward.

6. The gyroplane has simple structure, low stall speed and short taking off distance, so it is very popular.

7. Gyroplane is different from the helicopter. Its rotors are not linked to the engine and cannot provide pulling force and controlling moment.

8. An information collecting technology based on unmanned gyroplane was trially tested. The characteristics of geometric distortion from acquired images and their correction methods was introduced.

9. In order to improve the testing technique of the gyroplane rotate speed adjustin...
