1. Main rotor is the key part of helicopter modeling, the associated modeling methods of aerofoil aerodynamic loads, rotor inflow dynamics and blade flap motion are discussed in detail.

2. On the Main Rotor system, they went with an all metal Swashplate with adjustable lower Swashplate ring so your Beam would never develop a sloppy feel.

3. European helicopter's main rotor blades four, non - bearing and high - strength fiber composite materials.

4. A composite main rotor yoke is used in an example problem to demonstrate the reliability analysis.

5. The three-blade main rotor is mounted above centre of fuselage.

6. For the classical helicopter of single main rotor with tail rotor,(http://sentencedict.com/main rotor.html) the effect of inflow models with different characteristics on helicopter trim and digital simulation were discussed in this paper.

7. The x3 has a five-bladed main rotor and a pair of propellers on two short wings.

8. Additionally walking into the tail rotor or main rotor is a safety concern for bystanders.

9. Vertically mounted engine driving main rotor via toothed belt as second-stage reduction gear .

10. And its main rotor pump rotating parts should be static balance and dynamic balance test.

11. If this attitude can be maintained throughout the roll, then the model will be continuously pulled forward by the main rotor.

12. At the time of writing, however, the ideal design of the main rotor blade was still to be established.

13. This means rolling to the right with a clockwise main rotor or to the left if the rotor rotates anticlockwise.

14. The helicopter warning horn then sounded advising that the main rotor blades were too slow.

15. Some models will drop very rapidly during the early part of the descent while the main rotor winds up to a suitable speed.

16. I have found it to be a great help if the main rotor blades are covered with a glossy white material.

17. When tail rotor blade designed into soft in rotary plane, there is a new dynamical problem of coupling stability between tail rotor and tail boom for helicopters with one main rotor and tail rotor.

18. And centrifugal pump (pump milk) Comparison: centrifugal pump because of its simple structure, low cost and widely used. Compared with the main rotor pumps have the following differences.

19. Stainless laminated strips has usually been selected as a load - bearing structure in main rotor hub and tail rotor hub of a helicopter.

20. One of 19 AS550s in Brazilian army service, it sustained substantial damage to its main rotor and Turbomecca Arriel 1D engine as it came to a rest on its side against a mound of earth.

21. For wind turbine, we can dectect the speed as well as the direction of main rotor , gear box, generator, speed measurement of the brake disk.

22. And it is proposed that much improvement of the range profiles can be achieved by using the vibration compensation of the main rotor of the helicopter in forward flight.

23. U.S. Naval Air Systems Command (Navair) has issued a temporary grounding bulletin on six UH-1Y Hueys and one AH-1Z Cobra due to extensive damage to the main rotor gearbox on two of the new Hueys.

24. This means it can hover like a helicopter, but when flying forwards can reduce the speed of the main rotor and let the wings provide part of the lift. Its propellers give the extra oomph.

25. Starting off with vortex tube theory, the relationship between the angular rates and the first harmonic inflow is deduced, and then the generalized model of main rotor dynamic inflow is modified.

26. Adding a rotor blade (it had five on the main rotor and four on the tail) and using a modified exhaust system were among them.
