@@minckhoz What If The Gears Brake Down?

The video didn't talk about the unique control system. On most helicopters the controls are connected to a big swash plate underneath each rotor which can rotate the entire blade (changing its pitch angle) throughout each revolution of the rotor. On the K-max the rotor blade angle is fixed at the root of the blade, and control linkage runs up through a very small swash under the hub then linkage continues inside the blades out to the servo flaps. They work similarly to elevator and rudder trim tabs. When the flap goes up, the rear of the blade goes down, increasing the overall angle of attack of the blade and vise versa. But because the rotors are fixed at the root, the blade must twist to accomplish this this. That means the K-max blades are twisting and untwisting with every rotor revolution. Yaw control: on a traditional non-intermeshed tandem rotor helicopter (Chinook) when you want to induce yaw, you can tilt one rotor right and the other left creating a large yaw moment. On a coaxial helicopter (various K-maxx) you increase the collective of one rotor and decrease it on the other. The rotor producing more lift produces a greater torque reaction and the aircraft rotates the opposite direction while net lift produces is about the same. The K-maxx does both of these at once. It increases the collective of one rotor and decreases the other, while also tilting one rotor forward and the other back with differential cyclic inputs. All of this is handled with mechanical linkages, with no hydraulics.

I have always wondered if this rotor system is more efficient than a coaxial counter rotating rotor system that also does not need a tail rotor.

The servo flap does not act like the flap on an airplane. An airplane flaps increase lift and drag to allow for slower steeper approaches. Also helps reduce takeoff distance. The K-Max servo flap is used to eliminate hydraulic flight controls. The servo flap, moved by the pilot's flight control inputs, changes the pitch of the blades. If the servo flap moves down the blade pitch is reduced and if the flap moves up the blade pitch is increased.

This is an absolutely brilliant design and bmy absolute favorite helicopter!

For all the naysayers , in the 50's , it was the most efficient helicopter made , was not made for speed , but made for lifting . I just knew we were not done w/ huskie and Charles Kaman is a genius, long live the Pedro . It may be the only one not named after an indian tribe

@NiekLipper

5 жыл бұрын

@Brian Foote when talking about wings or wing-like structures, as is the case with a helicopter, lift is the force created by that structure perpendicular to the flow of the fluid (air). This force has to to be big enough to get the body of the helicopter of the ground and in this case carry an additional load. Therefore, when talking about aeroplanes or helicopters it's standard practice to include the vehicles weight in the maximum lift capacity. So it's not about me learning the English language but more about you knowing your physics

Spectacular heli. For heavy lift it would be nice to have two engines of course. But being an aerial truck you want to control the cost. Two engines and a heavier, more complex transmission would probably not be practical. It's a niche market, but this thing is unmatched at what it does.

I'd love to test one of these.

The reality is the K-Max (which entered production in 1991, was produced until 2003 and re-entered production in 2015) is actually more mechanically complex than traditional designs, and more expensive to maintain. That's why Kaman's designs have never been commercially successful, although the US military operated a couple of them. 38 K-Max helicopters were built in the initial run, 11 of them have crashed and 5 are in storage. An additional 3 have been built since production restarted (with 7 more on order). That's not exactly lighting the world on fire.

@hart-of-gold

Much less complex control linkage and thrust bearings for the rotors. The interference caused by the wash of 1 rotor on the other is the same for both rotors. Also the rotor heads in a synchropter need to adjust for the motion of the helicopter much less than normal separated rotors (tamdem, side by side or main & tail) to balance lift because of the different airspeeds of the blades of a moving rotor. Coaxial craft share this advantage. Lift differences are hard to say because intermeshing rotors by design need their rotors on different axes reducing lift, but the simpler bearing and swash plates mean less power is lost. My guess is coaxial rotors generate more lift but intermeshing rotors are easier to build.

Now lets everybody try do do it with our arms at home. It is funny :)
