Below check the specific characteristics of the helicopter or eVTOL you are looking for. You can select multiple items for each characteristic. The results will be filtered automatically.
The world's first mass-produced helicopter has a square fuselage cross section. The fuselage of the R-4 gradually tapers into the tail boom. It has no vertical stabiliser, but an open frame that holds the tail rotor on top. The tail wheel it attached to the middle of the tail boom by long struts.
Basically an R-4 with a new fuselage and tail boom, the R-6 has a typical appearance. When on the ground, it is supported by the two main gears at the lowest point, and a tail gear under the long, pointed tail boom. The front fuselage points up and has a small wheel underneath as well. The R-6 has no horizongtal or vertical stabiliser.
As the fixed wheeled gear can have different configurations (tail, nose and four legs), the main characteristic is the fuselage cross section. This is a triangle with rounded corners: the top of the fuselage is wider than the bottom.
With its rounded fuselage the Sikorsky S-52 looks a bit like an Alouette 3 with four, single wheeled gears, but then with a covered engine (in the fuselage). Its horizontal stabilisers have significant anhedral.
The S-55, also known as H-19 and Westland Whirlwind, has the engine in the nose. This is connected through the cabin to the three blade main rotor. The cockpit is above the cabin, in front of the rotor mast and above the engine. The las key feature is the four leg gear.
On this photo the S-56 has no rotors, but without you can still easily see the key features: engine nacelles placed on pylons attached to the top middle of the fuselage, that also hold the long two wheel retractable main gears. In the nose, below the cockpit, are clamshell doors with windows.
Typical features of this helicopter are the boat shaped underside of the fuselage, enabling water landings, and strut-braced sponsons at the end of small stubs. The latter provide stability in the water and hold the retracts gear. The single wheel tail gear is not retractable.
This derivative of the S-61/Sea King has a loading ramp at the rear of the fuselage, large sponsons and an all two wheel nose gear. They have a five blade main rotor, a tail rotor on the left and a high mounted horizontal stabiliser on the right.
The S-64/CH-54 was designed to carry heavy load and therefore has a short forward fuselage with cockpit. For the rest it is essentially a frame holding the two engines and main rotor, and long legs for the main landing gear. The helicopter has a six blade main rotor and four blade tail rotor. A pod can be attached under the fuselage.
The biggest helicopter in the western world has six to eight main rotor blades, three engines on top of the fuselage, a tail rotor on the left side of the tail and a high mounted horizontal stabiliser on the right. Also characteristic are the large sponsons at the side of the fuselage, and the straight top of the fuselage, from cockpit to tail.
