Experimental helicopter by Dr. Boothezaat in 1923

I'm reading through old Time Magazine issues. The March 1923 issue discusses Thomas Edison sending Dr. Boothezaat a congratulations for a test of a helicopter by remaining in the air for 2 min 45 sec at a height of 15 feet. Also see https://time.com/vault/issue/1923-03-03/page/23/. — Preceding unsigned comment added by Noloader (talk • contribs)

I want to edit something because it doesn’t seem right and giving wrong information about helicopters. You should have also all the answer to helicopters

This edit request has been answered. Set the |answered= or |ans= parameter to no to reactivate your request.

The following phrase, whilst partially correct, is misleading:

"

Most helicopters have a single main rotor, but torque created by its aerodynamic drag must be countered by an opposed torque"

[Suggested Correction]: Aerodynamic drag affects the entire aircraft. Specifically, the aerodynamic drag experienced by the rotor blades is transmitted to the airframe by an equal and opposite 'reaction torque' via the rotor drive shaft and hence the engine mounts. Unlike an automobile engine, in which the. car body cannot rotate in response to this torque, a helicopter is free to rotate around the rotor drive shaft axis. A tail rotor, 'anti-torque rotor', is therefore necessary to establish a balancing (anti-)torque to prevent the airframe from spinning around the rotor axis.

Suggest the text is amended accordingly. 86.26.142.91 (talk) 10:49, 12 June 2024 (UTC)[reply]

Not done: please provide reliable sources that support the change you want to be made. Lightoil (talk) 15:28, 12 June 2024 (UTC)[reply]
