Proposed Improvement to VTOL Tiltrotor.

Proposed Improvement to VTOL Tiltrotor.

Proposed Improvement to VTOL Tiltrotor.

This post relates to a VTOL concept and not a specific engineering question. Should this violate the policies of Eng-Tips, I will understand the reason for its removal.


The Web page http://www.unicopter.com/1471.html presents a concept that is theoretically an improvement over the current tilt-rotor. Critiques or contributions to this open concept will be appreciated.

RE: Proposed Improvement to VTOL Tiltrotor.

Take a look at US pat. 6655631.  

It shows a similar rotor configuration and makes mention of electric drive,  but does not make claims regarding drag reduction benefits of in-line rotors in a/p mode.  I just skimmed over the patent text, so maybe I missed something.

ps. Will you be at the AHS forum in Montreal?

RE: Proposed Improvement to VTOL Tiltrotor.


Thanks for mentioning the patent on a hoverplane with four tiltmotors.  It will be interesting to read and see what they propose for the various aspects of vertical and horizontal flight.

I will not be attending the forum in Montreal. Perhaps next years.

Thanks again.
