Helicopter speed 250 kilometers per hour power, because the conventional design of the helicopter general speed can fly about 250 kilometers per hour, advanced military helicopters as fast as 350 kilometers per hour or so, the United States Sikorsky launched a new generation of high-speed attack helicopters X2 with counter-rotating rotor blades and the combination of the tail propeller program, the performance of the performance is greatly improved, the maximum speed of up to 463 kilometers per hour.
Helicopters are slower than ordinary airplanes mainly because they are limited by their use of roof rotor layout design, compared to fixed-wing aircraft, receiving less forward thrust, it is difficult to form a high-speed mode.
Advantages of helicopters.
The outstanding features of helicopters are that they can do maneuvering flight at low altitude (several meters above the ground), low speed (from hover) and constant nose direction, especially vertical takeoff and landing in small sites. Because of these characteristics, it has a wide range of uses and development prospects. In the military has been widely used in ground attack, aircraft landing, weapons delivery, logistical support, battlefield rescue, reconnaissance patrol, command and control, communications, anti-submarine minesweeping, electronic countermeasures.
In civil applications, it is used in short-distance transportation, medical care, disaster relief, emergency rescue, lifting equipment, geological exploration, forest protection and firefighting, and aerial photography. The transportation of personnel and materials between offshore oil wells and bases is an important aspect of civilian use.
How many kilometers per hour is the typical speed of a typical helicopter?1. Conventional design helicopters can generally fly about 250 kilometers per hour helicopter speed, the fastest advanced military helicopters can fly about 350 kilometers per hour.
2. The U.S. Sikorsky launched a new generation of high-speed attack helicopters X2 using a combination of counter-rotating rotor and tail propeller program helicopter speed, performance greatly improved, the maximum speed to helicopter speed reached 463 kilometers per hour.
3. Inside the transport aircraft: Ka-27 (Kamov-27), maximum speed 315 km/h.
4. Armed helicopters: Ka-50 (Ka-50 "Black Shark"), maximum speed of 293 km/h.
5. Smaller civilian aircraft: McDonnell Douglas MD520N , maximum speed of 250 km/h.
< p> Expanded:
Helicopters, as one of the most distinctive creations of 20th-century aeronautics. It has greatly expanded the range of applications of helicopter speed. The helicopter is a typical dual-use product, can be widely used in transportation, patrol, tourism, rescue and other fields.
The maximum speed of the helicopter can be up to 300km/h or more, swooping limit speed of nearly 400km/h, the practical limit of lift up to 6000 meters (the world record for 12450m), the general range of up to 600 ~ 800km or so. The general range can be 600-800km. The range can be more than 2,000km by carrying inboard and outboard fuel tanks. According to the different needs of the helicopter has a different takeoff weight. Currently the world's largest heavy helicopter in use is the Russian Mi-26 (maximum takeoff weight of 56t, payload 20t). The current practical application is the mechanical drive type single-rotor helicopter and double-rotor helicopter, of which the single-rotor helicopter is the largest number.
Reference:
The speed of a helicopter is about 300 kilometers per hour.
1, the mainstream use of helicopters maximum speed of about 300km / h, the general cruising speed of 200-240km / h, the maximum speed of transportation class helicopters to be a little slower. Also mention that the helicopter's speed is not its strong point.
2, helicopter flight mainly rely on the rotor lift and engine power. Helicopter lift limit is positively correlated with air density and engine power, and the increasingly thin air at high altitude has a great impact on lift efficiency. A helicopter is an aircraft that flies with uplift and propulsion provided by at least two or more horizontally rotating rotor blades, invented in September 1939 by Sikorsky.
What fuel does a helicopter burn:
Depends on the situation. If the helicopter's engine is an aviation turboshaft engine, the fuel used is aviation kerosene; if the helicopter's engine is a piston aviation engine, the fuel used is gasoline. In addition, helicopters can not add diesel fuel, because diesel engines belong to compression ignition mode of operation, the engine piston cylinder pressure resistance to high temperature, so the diesel engine is relatively heavy gasoline engines, and diesel engine piston connecting rod stroke is long, low speed.
Helicopter speed how many kilometers per hourConventional design of the helicopter speed of about 250 kilometers per hour, the fastest advanced military helicopters can reach about 350 kilometers per hour.
Helicopters, as one of the highly distinctive creations of aviation technology in the 20th century, have greatly expanded the range of applications for flying machines. The helicopter is a typical dual-use product, which can be widely used in transportation, patrol, tourism, rescue and other fields. The maximum speed of the helicopter can reach more than 300km/h, swooping limit speed of nearly 400km/h, practical ceiling up to 6000 meters (world record 12450m), general range up to 600-800km or so. The general range can be 600-800km. The range can be more than 2,000km by carrying the in-flight and external fuel tanks. The current practical application is mechanically driven single-rotor helicopters and dual-rotor helicopters, of which the number of single-rotor helicopters is the largest.
How fast can a helicopter fly at Mach?The maximum speed of transport helicopters is a little slower. Tilt-rotor aircraft such as the V-22 maximum speed of 509km/h, the maximum speed of passenger aircraft still in service is generally not more than 1,000km/h, regional airliners are basically between 600~700, all of them are subsonic aircraft. Specific models of takeoff and landing speed, Boeing 737 VR for lifting the front wheel speed, that is, takeoff and landing speed, is 153 knots, converted to 283 km / h. 1958 fighter speed more than Mach 2, even now the speed of fighters is also in the Mach 3 under, which has reached the speed limit of the jet engine helicopter speed Helicopter speed.
If the rotor blade length of 16 meters Mi-26, the speed is only 130 rpm. With that wingtip it's all up to the Mach 0.6 limit. With a light rotor helicopter like the V22 Fishhawk, helicopter speed he's in the cruise phase when the rotor blades are in the forward direction, generating lift through the wing, and the rotor blades are providing the pull. The Su-27, for example, has a maximum speed of 2500 km/h (Mach 2.35) at high altitude and 1400 km/h (Mach 1.15) at sea level.
Helicopter speeds are generally in the range of 200 - 350 kilometers per hour. Approaching Mach 0.7, it moves horizontally at 10 m/s and climbs at 3 m/s, with enough lift to be able to conduct aerial reconnaissance near the Mars rover's landing area. Its maximum flight speed reaches over Mach 2. The Mi24 helicopter, on the other hand, is a subsonic helicopter. The rotor speed is actually limited by the speed of sound, and the linear speed of the paddle tips can't exceed Mach 0.85, or drag will increase dramatically.
The Stinger missile is guided by infrared light and attacks in all directions based on the heat flow of the aircraft's exhaust. It has a range of up to 4,800 meters and flies at two times the speed of sound. It is the world's first fighter to exceed Mach 3 speed, with a maximum flight speed of Mach 3 (there is also the MiG 25, which exceeds Mach 3.2).
