Intermeshing rotored helicopters have high stability and powerful lifting capability. The latest Kaman K-MAX model is a dedicated sky-crane design used for construction work, and has been modified for trials by the USMC as an optionally-unmanned cargo transporter. Unmanned aerial vehicles with intermeshing rotors have also been flown. [2]
The first aerobatic manned drone, as this type of electrically powered multi-rotor helicopter is known, had 12 rotors and could carry 1-2 people. [37] Manned drones or eVTOL as they are called typically multirotor designs powered by batteries gained increasing popularity and designs in the 2020s. [38]
The two rotors were synchronised through a shaft to prevent blade collision, allowing the aircraft to operate through only one engine in the event of an emergency. In that case, the remaining engine would automatically run up to double power to compensate. [4] Bristol attempted to market a civilian variant of the helicopter, designated the Type ...
The Airbus Helicopters H145 (formerly Eurocopter EC145) is a twin-engine light utility helicopter developed and manufactured by Airbus Helicopters.Originally designated as the BK 117, the H145 is based upon the MBB/Kawasaki BK 117 C1, which became a part of the combined Eurocopter line-up in 1992 with the merger of Messerschmitt-Bölkow-Blohm's helicopter division of Daimler-Benz into Eurocopter.
Bell announced its new project after the Bell 429 and Bell V-22, the super medium Bell 525, previously it was known as Project X or Magellan. The Helicopter is overall designed for trips of 50 to 500 nautical miles, and has a 5-blade main rotor powered by twin engines, digital controls and Garmin G5000H screen, with planned seating for 16-20 people.

Tokyo Metropolitan Police Department EH101 (AW101) The BERP rotor blade design was developed under the British Experimental Rotor Programme.The initial BERP rotor blades were developed in the late 1970s to mid-1980s as a joint venture programme between Westland Helicopters and the Royal Aircraft Establishment (RAE), with Professor Martin Lowson as a co-patentee.

Rotor's nearly $1 million Sprayhawk helicopter is a Robinson R44, but the four seats have been replaced with flight computers and communications systems allowing it be operated remotely. It has five cameras as well as laser-sensing technology and a radar altimeter that make terrain reading more accurate along with GPS and motion sensers.
The Bratukhin Omega (also known as the 2MG) was an early Soviet helicopter, the first product of a new Soviet design bureau, OKB-3 that was created from within TsAGI specifically to develop rotary-wing aircraft. Bratukhin's design was a transverse rotor aircraft, with each rotor carried on a long outrigger truss. The Omega's rotors were each ...
