What is the speed of the aircraft? What is the speed of flight?

The speed of the aircraft has been and remains a very important factor of his, which allows not only more comfortably move between cities, regions or countries, but also makes the flight time as fast as possible.

The first civilian aircraft, "Ilya of Murom" had airspeed just 105 kilometers per hour, this limit today could easily be overcome to a conventional car, and in some cases at the international bus and therefore, comfortable such movement can not be called.

With regard to conventional passenger planes, their airspeed It has already exceeded 500 kilometers per hour, and is not the limit, but as it turns out, and this is far from the real comfort.

flight speed

Modern passenger aircraft lost pleasure to fly at supersonic speeds, and, with it had very good reasons are the following factors:

  • Reliability. When flight at supersonic speeds, the plane has to be streamlined as much as possible, and as you know, the longer the aircraft, the more difficult to achieve. Otherwise, the plane when it reaches supersonic speeds can literally fall to pieces, which naturally is unsafe and can carry disastrous consequences.

  • Cost. Essentially, supersonic aircraft have low fuel economy, and hence they are low cost much more expensive than slower airliners.

  • Narrow specialization. Under this factor should be understood that not every airport will be able to afford to take a supersonic airliner because of its large mass and speed, that is, need more runway.

  • Frequent maintenance. In view of the fact that the aircraft moves to the superfast speeds. It is necessary to constantly maintain, that is, almost after every flight to check the condition of the fuselage, rivet fastening, etc., which also carries a number of inconveniences for air carriers.

If the speed of modern aircraft of civil aviation is about 800 kilometers per hour, then the supersonic passenger aircraft, it was more than 2100 kilometers per hour, which is more than 2.5 times faster than today's air travel. However, referring mainly to security, to date there is no existing supersonic passenger airliners, which just something in the history of civil aviation, there were two - a Soviet Tu-144 and the Anglo-French "Concorde".

It is possible that in the near future, we will again observe supersonic aircraft in the sky, and it is worth noting a number of aircraft manufacturers and design offices working on this issue. However, to expect any innovations in the next few years it is not necessary, if only because of the fact that the important factor remains the safety of passengers, the speed of the aircraft It counted only then.

It is known that different models of aircraft have different flight speed. Thus, combat attack aircraft have significantly higher speed performance than the devices of civil aviation.

Speed ​​performance of passenger airliners

  • Tu-134 a passenger liner for short-haul flights. The maximum number of passengers on board - 96 people. Cruising speed of the machine is 850 km / h.

  • Tu-154 designed for medium-haul flights at. On board may be up to 180 passengers. This cruising speed of the machine is 950 km / h.

  • Tu-204 - Medium-range airliner, which can carry up to 214 passengers on board. Optimal speed flight is 850 km / h.

  • Boeing-747 It has a cruising speed in 917 km / h. The machine is able to perform long-range transport to 298 people.

  • Boeing-777 also makes long flights, but the number of passengers in the cabin reaches economical option only 148 people, and the optimum airspeed indicator is in 891 km / h.



Nevertheless passenger planes have low maximum speed and cruising flight, although there are exceptions to the rule. For example, the aircraft "Concorde" or Tu-144 boast high-speed performance. Most recently, the corporation "Boeing" announced the creation of a new high-speed passenger system, which had previously been baptized as a Zehst. The plans of the company's management and designers to bring the speed of this model to 5029 km / h.

The highest speed of flight have a new war machines that reach supersonic speeds.

The fastest supersonic aircraft

Consider the concept of the speed of the aircraft with the physical side:

Speed. Speed ​​of motion of a body (including the aircraft) is the ratio of the length of the path traversed by the time during which the body passes this way. If movement occurs at a variable rate, it is possible to consider the average speed on a certain track section and movement speed at this time. In order to determine the speed at the moment must be taken sufficiently small time intervals. The smaller the time interval is taken, the more accurate will be determined by the speed at the moment.

The technique adopted to measure the speed in meters per second (m / s) and in kilometers per hour (km / h). In order to speed expressed in meters per second, converted to kilometers per hour, multiply the speed at 3,6.

For example, the speed of sound at an altitude of m 8 000 308 m / sec or 308 X 3,6 = 1108,8 1109 x km / h.

The true speed. The speed at which the aircraft is moving relative to air, called the true airspeed, or Vu.

True speed determines the amount of aerodynamic forces and moments acting on the aircraft.

In the absence of true wind speed is the same as the ground speed - the speed of the aircraft relative to the ground.

Indicated airspeed. In aeronautical engineering is widely used speed detection using the difference between the measurement of total and static air pressure. Receiver full pressure is a special nozzle (tube) fitted on the airplane (for example TA-156). Static pressure is generally supplied to the intake unit of which is a fitting hole in one point of the fuselage. Speed ​​measured in this way is called airspeed mgmt.

Retrograde that the decrease in the density of air at a constant true airspeed will be accompanied by a decrease in the velocity head and, consequently, a decrease in airspeed.

The rate is not perfectly accurate tool. In his testimony is necessary to introduce an amendment instrumental B Receiver static pressure also is not ideal - on the measurement of the pressure affects the air pressure disturbance at the location of the receiver.

The vertical axis lies in the plane of symmetry of the aircraft and is directed toward the upper surface of the wing. The high-speed system O y axis is perpendicular to the axis O *. The coupled system axis is perpendicular to the basis.

The transverse axis is directed toward the right wing.

The angle between the direction of the flow velocity and the plane of the wing chord is called the angle of attack as well.

The angle between the direction of the flow velocity and the plane of symmetry of the aircraft called a grazing angle.

Overload n is the dimensionless ratio, which shows how many times the sum of all forces acting on the body (except gravity) is greater than body weight. If an overload is zero, it means that the body acts only unbalanced force of gravity, and the sum of the remaining forces is zero.

Speed ​​helicopters

Speaking of the high-speed characteristics of the aircraft, not to mention helicopters. Due to the large number of manufacturers and building schemes have different performance speeds.

Speed ​​helicopters depends on a huge number of parameters. The most compelling are the weight of the unit, the number of rotors and the number of motors which drive screws.
