12. Reduction & Elimination of Common Helicopter Flight Hazards
The U.S. Department of Transportation has published a ˇ§Basic Helicopter Handbookˇ¨. One of the chapters in it is titled, ˇ§Some Hazards of Helicopter Flight'. Ten items of hazards have been listed to indicate that a typical single rotor helicopter has to deal with. The unique EzyCopter's coaxial design either reduces or completely eliminates these hazards. The following list indicates which:
|
1. Settling with power |
Reduced |
|
2. Retreating blade stall |
Eliminated |
|
3. Ground resonance |
Eliminated |
|
4. Low-frequency vibrations |
None |
|
5. Medium frequency vibrations |
None |
|
6. High frequency vibrations |
None |
|
7. Transition from powered flight to autorotation |
Eliminated |
|
8. Anti torque system failure in forward flight |
Eliminated |
|
9. Anti torque system failure while hovering |
Eliminated |
|
10. Height-Velocity Curve |
Eliminated |
_
The reduction and elimination of these hazards are the strong points for the EzyCopter safety design, and one of the primary reasons why the EzyCopter will prove to be a revolution in the personal helicopter world. The final question lies in the affordability. And that is what the EzyCopter by Yoshine has promised to deliver. |
