The Kaman K-MAX is the world's first helicopter specifically designed and certified for external lift operations.

The external cargo load helicopter was developed by Kaman Aircraft and designed to lift a payload of over 6,000 pounds . That is more than the helicopter's empty weight and almost twice as much as the "Bell 205" helicopters.

It uses a unique single-engine double-rotor system in which two intermeshing rotors (synchropter) cross each other.

This eliminates the need for a tail rotor found in conventional helicopters that is designed to hold it straight and to prevent it from spinning around in the opposite direction of the main rotor blades.

The K-MAXs two opposite-spinning and crossing rotors ensures a high lift performance in hot and high conditions than conventional helicopter .

The K-MAX can be parked in a narrow area by aligning the blades sideways instead of crossed.







It uses an average of 85 gallons or 321.7L of fuel per hour during lift operations and cost $1,200 (N436k) per flight hour to operate.

It has a maximum airspeed of 185 km/h with an external load and 148.2 km/h without it .

The 7 - 8.5 million dollars helicopter is used by firefighters, construction firms and the military.





A self-flying or pilot-less K-MAX version was jointly developed by Lockheed Martin and Kaman .

It was designed to be a life saver as it can take supplies and equipment to battle locations (especially in Afghanistan with over 600 unmanned missions and over more than 700 flight hours) and also bring loads back to the main base, thereby reducing the amount of ground convoys.

some times I just wondered how Buhari became the president

Nice innovation!

Wow

Nigerian will have to sell everything in the south before they could be able to ................. that #onlyGodknows

Nice one

Since it can be controlled remotely and unmanned, I think our clueless Nigerian Army can use it in fighting Boko Haram.

But the Chief of Army Staff and NSA will still embezzle the funds.

See the blades. The way they cut through air reminds me of the way Atiku was cutting his way into the treasury when he was VP

Fancy design though..

Hope y'all know it wont fly on one blade...

Sweet... Planes are beautiful.... I love them so much..

It called a semi coaxial rotor system where dual main rotors are spun at opposite direction and removes the need for a tail rotor to maintain stability of the fuselage frame ..

More than 400k per hour
If it will help lift buhary from aso rock I won't mind paying though

What is the advantage of the intersecting blade? is it just a design feature?
