How much thrust is required to take off?
The thrust needed to sustain flight is about 1/18 of aircraft weight, and if you factor in the multiples given above, you will notice that if the aircraft can fly at full thrust in cruise, this fits nicely with a static sea level thrust force equivalent to one third of its weight force.
How much force does a plane need to take off?
For aircraft such as Boeing 737 and Airbus A320 family, takeoff is in the range of 130–150 knots*. For mid-size aircraft such as Airbus A330 and Boeing 757/767/777/787, takeoff is in the range of 140–165 knots*. For larger double deckers such as Boeing 747 and Airbus A380, takeoff is in the range of 145–175 knots*.
How much thrust does a 747 take off?
A Boeing 747-400 has a maximum takeoff mass of 396,890 kg (910,000 lb). It is powered by four Pratt & Whitney PW4062 turbofans that produce a maximum thrust of 275 kN each.
How much thrust does it take to lift a plane?
For an airplane, normal takeoff, you need about 70 pounds of thrust (rule of thumb 5:1). As the plane accelerates past stall speed, the power required to maintain flight is a lot less than for take-off.
How is engine thrust measured?
The goal of a turbofan engine is to produce thrust to drive the airplane forward. Thrust is generally measured in pounds in the United States (the metric system uses Newtons, where 4.45 Newtons equals 1 pound of thrust).
How many pounds of thrust does a 737 have?

How much thrust does a Cessna 150 produce?
Additional Data of Cessna-150: Weight of loaded: 680 kgs. Weight of Empty: 437 kgs. Wing loading: 9.4 psf (45.8 kg/m²) Power loading: 15 lb/hp (6.81 kg/hp) Maximum Engine Power: 100HP (75kW). Wing Span: 10.2 m.
What is thrust required?
Thrust is the force needed to overcome the resistance of air (drag) to the passage of an aircraft. In an aircraft, the thrust is generated in different ways according to the type of propulsion: Turbojet: all the thrust is generated in the form of jet efflux from the rear of the engine.
How much thrust is required for short take-off?
Assuming a non-accelerating level flight at optimal cruise speed 50 mph in no wind condition it will require at least 400 / 10 = 40 lb of thrust. Based on above numbers how to make rough estimate of the minimal thrust required for a reasonably short take-off (say within 500 to 1,000ft roll of runway)?
How much thrust is needed to fly a plane?
Using these specs then I can roughly assume that many specs have been taken into account for a thrust calculations. For ex. aircraft is gross weight 400 lb with L/D ratio of 10. Assuming a non-accelerating level flight at optimal cruise speed 50 mph in no wind condition it will require at least 400 / 10 = 40 lb of thrust.
How much thrust would it take to fly the A380?
In other words for each metric ton of weight you need around 9.81 kN of thrust. The A380 has a operational empty weight of 276 t so it would need 2707 kN of thrust to sustain a vertical climb. Its 4 engines each producing 320kN don’t even come halfway.
Why do airliners have such low static thrust?
Normally, the static thrust of an airliner is at least a quarter of its weight. If the airliner is empty, this can become as much as half of the weight. One reason is altitude capability: Since thrust goes down with the density of air, the static thrust in the cruise altitude is only a quarter of sea level thrust.
