With an increase in torque n angle of attack, you're also increasing drag, therefore you need more power/torque. And of course, too much angle of attack without sufficient power will cause blade stall. Hasta la vista Baby!

I just started the video so I don't know if Dr. James Wong will address my question of: why do some helicopters have 2 lifting blades (Bell Heuy, Cobra) and some have 4 (Apache) and some have 7 (CH-53, mil-24 HIND)? Others will have 5 or 6 or whatever, I just want to know what is the purpose of using more than 2 lifting blades.
@HonestYu Жыл бұрын
Generally, more blades can decrease the vibration level of a helicopter. And fewer blades mean higher blade loading, which is not feasible for heavy-lift helicopters such as the CH-53s. Furthermore, the blade number is related to the spanwise blade chord distribution, which affects the rotor performance by changing the spanwise lift distribution. Besides, the helicopter's rotor blade design should base on the special mission requirement. For example, the AH-64's and UH-60's blades' chords should be wide enough to gain damage tolerance. Still, the rotor rotation speed should be as low as possible to reduce the noise level. And lots of actual requirements make the designers decide on the final blade number.
@Pork-Chopper Жыл бұрын
@@HonestYu Also, the larger the cord, or width of the blade (the wing) the more lift it can produce compared to a rotor with a smaller cord or width... A larger cord/width moves more air than a smaller width, and can do so at lower rpm. A smaller cord or width would need to spin at a higher rpm to produce more lift...

Eliminate the rotor blade tips. Eliminate the stators. Eliminate physical contact points. The way you do this is so absurdly simple. Like "Damn! Kick me in the balls for not seeing that!" simple. Great video, though. I strongly suspect what you covered is going to largely become "obsolete" very soon. But it's equally important to earn one's "chops" re: the physics & engineering math. So Kudos for helping our next-gen engineers be better ones. I'm not sharing more because the patents are not yet formal. You'll know it when you see the public intro of 3 eVTOL craft. The Woof-Cub, the Aero-Woof, & the Battle-Woof. My tributes to Air Wolf. They are... A 24' (12,000 lb) private executive 6-seater. A 34' (17,000 lb) search & rescue utility craft. A 44' (22,000 lb) military insertion-extraction craft. The Woof-Cub Max TOW = 16,000 lb. Aero-Woof Max TOW = 30,000 lb. Battle-Woof Max TOW = 42,000 lb. I want y'all to remember you heard about this when the reveal goes public. And... May the Force (=MA) be with You :)

I have been designing a VTOL high altitude aircraft that is different to everything currently available to fly at 26000m. While designing it I needed to control yaw at low altitudes. This gave me a great idea for the yaw control of a helicopter, another design that has not yet been used, being more efficient and simple than current designs. I hope to set an altitude record for the helicopter first of 13500 metres HOGE, not forward flight. People do laugh, but it is true, if it can be dreamt, it can be built.

I feel like you're already decades ahead of what anyone would come up with. Seems to me like you already know what you're looking for. So why are asking for people who know less about the subject than yourselves for help designing something we have no experience with? Doesn't make sense to me.

"The density of air or atmospheric density, denoted ρ (Greek: rho), is the mass per unit volume of Earth's atmosphere. Air density, like air pressure, decreases with increasing altitude. It also changes with variation in atmospheric pressure, temperature and humidity."
