How much power does it take to fly an airplane?
The power required to keep a Boeing 737-300 flying at a constant altitude and speed is 7.2 × 10 6 watts. The rate of fuel burn necessary for the engines to produce enough power to keep the airplane flying can be calculated from the total power requirement.
How to calculate the minimum power of an aircraft?
Figure 13.3:Typical power required curve for an aircraft. The velocity for minimum power is obtained by taking the derivative of the equation for with respect to and setting it equal to zero.
What is the power required for steady level flight?
Now we can look at the propulsion system requirements to maintain steady level flight since and Thus the power required (for steady level flight) takes the form of Figure 13.3. Figure 13.3:Typical power required curve for an aircraft.
What are the equipment requirements for an airplane?
(d) A power failure warning device or vacuum indicator to show the power available for gyroscopic instruments from each power source; (e) An alternate source of static pressure for the altimeter and the airspeed and vertical speed indicators;
How much does it cost to have an IFE system on a plane?
This cost can be anywhere from $2 million to $5 million for a plane to be equipped with a set of seat back LCD monitors and an embedded IFE system. Some of the IFE systems are being purchased already installed in a new aircraft, such as the Airbus A320, which eliminates the possibility of having upgrade difficulties.
How is the energy of an aircraft calculated?
Power Requirement to Keep a Jet Aircraft in the Air. The total energy of an aircraft flying in the atmosphere can be calculated using equation 1. [2] E = ½ m v 2 + mgh. A Boeing 737-300 has a maximum takeoff weight of 5.65 × 10 4 kg, a cruise altitude of h = 10,195 m, and cruise speed of 221 m/sec.
How much power does a Boeing 737 take to fly?
Assuming that a Boeing 737-300 has a similar glide ratio to a Boeing 747 of 17:1, a Boeing 737-300 has a descent speed of approximately (dh/dt)= (221m/sec)/17 = 13 m/sec. The power required to keep a Boeing 737-300 flying at a constant altitude and speed is 7.2 × 10 6 watts.
