| 11. | For additional protection, he invented a system consisting of aerodynamic brakes on the blade tips.
|
| 12. | This blade design improves aerodynamic efficiency at the blade tip and reduces the acoustic signature.
|
| 13. | Bell immediately fitted the two-bladed rotor with tapered blade tip caps for the company's own independent testing.
|
| 14. | They spin grass blades and feed inside the spiral spinning, causing whitening of the grass blade tip.
|
| 15. | The test equipment measures the force at the instant the blade tip produces a sustained slash through the vest.
|
| 16. | If a crack is present pressure is lost and a red indicator on the rotor blade tip was tripped.
|
| 17. | The leaves are lanceolate, erect-spreading, sometimes falcate, with full margins, to cut up against the blade tip, with emerging veining.
|
| 18. | By increasing the rotor diameter with an additional modular segment that is applied over the blade tip, yield grows significantly.
|
| 19. | This implies a higher high-pressure shaft speed, to maintain the datum blade tip Mach number on the rear compressor stage.
|
| 20. | The leaf rib is cut in the upper part, emerging from the back as a short spike from the blade tip.
