Some Of The Best Future Helicopter Designs

Eurocopter X3

The X3 demonstrator is based on the Eurocopter as 365 dolphins helicopter with the addition of short-span wings each fitted with a tractor propeller having a different pitch to counter the torque effect of the main rotor conventional helicopters use tail rotors to counter the torque effect but the Eurocopter’s tractor propellers are gear driven from two main turboshaft engines which also drive the five-bladed main rotor system the helicopter is designed to prove the concept of a high-speed helicopter which depends on slowing the rotor speed by up to 15 percent in order to avoid drag from the advancing blade tip and to avoid retreating blade stall by unloading the rotor while the small wing provides 40 to 80 lift instead the X3 can hover with a pitch attitude between -10 and plus 15 degrees its bank range is 40 degrees in hover and is capable of flying at bank angles of 120 to 140 degrees which is beyond the capabilities of current tried and models in use today the chopper can climb at a speed of up to 5 500 feet per minute perform high g turn rates of 2gs at 210 knots enogh to make even the most seasoned pilots a bit dizzy this concept is well suited for missions requiring long transit flights at high speeds while retaining full vertical lift and hover capabilities

Sikorsky SARA

The Sikorsky SARAH takes a nod from Tesla’s cars it has full autopilot and is controllable from a large tablet surface mounted inside the cockpit you can load in a preset mission or just point to a spot on the map and enter your speed and altitude preferences the computer then calculates the best route to get there safely with a simple tap of the screen the helicopter takes off and goes to work along the way inertial guidance systems and GPS keeps it on track while external sensors including lidar and cameras watch for obstacles and potential landing sites should something go wrong along with the tablet the Sarah comes with two interceptors on either side of the flight seats these hand controls let the pilot interrupt the flight plant to change the helicopter’s direction or position or just fly around left control manages the throttle and saw the right is a joystick the allows for horizontal control pitching forward backward left or right even these thoufh are far simpler than a helicopter’s standard controls the cyclic throttle collective and pedals when the pilot uses the interceptor the computer finds the right combination of controls to derive they want the result is a control system that’s as intuitive as any video game

Sikorsky S-97

The Sikorsky S 97 is a responsive dream for experienced pilots it holds a nose-down hover something conventional helicopters can’t do without drifting which improves visibility to ground objects and is made possible by the rear propeller having two rotor discs spinning in opposite directions balances the effect that allows for much higher top speeds because the counter-rotating rotors also the torque typically generated on the fuselage by a single rotor there’s no need for a conventional rear tial rotor so in the radar the engineers replaced the side facing tail rotor with a rear-facing propeller that receives most of the power during forward flight with the two main rotors whirling just fast enough to maintain lift much like a wing conversely the rear prop is nearly underpowered and low speed maneuvering while the rotors are given all the power they need to ensure the two rotor blades don’t hit each other, so they don’t bounce and flex the way conventional helicopter blades do another of the raiders tricks is that it can slow down quickly and without pitching the nose up as conventional helicopters must since the rear prop eliminates the need to use the main rotor as a break similarly it can accelerate without pitching forward all of this also means the helicopter can point where it wants when it wants facilitating the crew’s aiming of weapons and sensors use of rescue equipemnt and whatever else they need to do


The MIL MIX-X1 is one of the fastest concepts on this list a projected top speed of over 320 miles an hour the helicopter will have a cruising speed of 280 miles per hour and a dash speed of 320 miles an hour this will be possible through the use of a pusher propeller and a number of aerodynamic improvements including a retractable landing gear and streamlined forward and rear fuselage section the MI X2 may be powered by two uprated kleemoff vk 2500 shafts or two future Klimov vk 3000 currently under development similar engines are installed on the mill mi 28 and come off ka 50 attack helicopters Russian air force general expects a prototype of fly in 2018 with production in 2022 Russian started a single sear flying laboratory based on the mill mi 24 in 2015 intended to go 248 miles an hour

Leonardo AW 249

Leonardo is developing this helicopter in a program called nice nuevo el Caters de espla escorts or a new reconnaissance and escort helicopter the aw 249 will be based on existing solutions and operational experience including a lightweight helicopter combat helicopter aw 129 mengusta but will be much heavier with a maximum takeoff weight of around 7 to 8 tons the weapons fit is constituting up to 16 guided anti-tank missiles 70 millimeter rockets as well as very short and short-range air to air missiles this implies the ability to carry a similar amount of weapons as the heaviest combat helicopters in the world the aw 249 stub wings will carry four weapon pylons and additional rails for air-to-air missiles the armament is to be completed with a 20-millimeter three-tube rotary gun successfully used today in the Mangusta.
