Which plane has the best thrust to weight ratio?
The most powerful commercial airline jets with four engines, the Boeing 747–8 and Airbus A380 have a thrust-to-weight ratio much less than 1:1. The 747–8, with a total of (4 x 72,300 pounds of thrust) 289,200 pounds of thrust, has a maximum takeoff weight of 975,000 pounds.
Is higher thrust to weight ratio better?
For most flight conditions, an aircraft with a high thrust to weight ratio will also have a high value of excess thrust. High excess thrust results in a high rate of climb. If the thrust to weight ratio is greater than one and the drag is small, the aircraft can accelerate straight up like a rocket.
What is the thrust to weight ratio of a Cessna 172?
213 kg thrust/909 kg weight = 23.3 \% thrust to weight ratio.
What aircraft has the most thrust?
The GE90-115B is powerful enough to fly GE’s Boeing 747-100 testbed with the other engines at idle, an attribute demonstrated during a flight test. According to the Guinness Book of Records, at 127,900 lbf (569 kN), the engine holds the record for the highest thrust (although rated at 115,300 lbf (513 kN)).
How much thrust does a Boeing 737 have?
What are two things that determine the thrust of an airplane? A high thrust to weight ratio means that the aircraft will have high acceleration and thrust and a high rate of climb….Beginner’s Guide to Propulsion. Thrust to Weight Ratio. Answers.
| Name of Aircraft | Thrust Per Engine in kN | Total Thrust Thrust per engine x engines |
|---|---|---|
| Boeing 737-300 | 88.9 | 177.8 |
| Boeing F18 | 47.2 | 94.4 |
How do you calculate thrust to weight ratio in aviation?
Aircraft. For aircraft, the quoted thrust-to-weight ratio is often the maximum static thrust at sea-level divided by the maximum takeoff weight. In cruising flight, the thrust-to-weight ratio of an aircraft is the inverse of the lift-to-drag ratio because thrust is the inverse of drag, and weight is the inverse of lift.
Can a plane take off with less thrust than its weight?
A plane can take off even if the thrust is less than its weight: if the lift to drag ratio is greater than 1, the thrust to weight ratio can be less than 1, i.e. less thrust is needed to lift the plane off the ground than the weight of the plane. For propeller-driven aircraft, the thrust-to-weight ratio can be calculated as follows:
What are two things that determine the thrust of an airplane?
What are two things that determine the thrust of an airplane? A high thrust to weight ratio means that the aircraft will have high acceleration and thrust and a high rate of climb. If the thrust to weight ratio is greater than 1, this means the aircraft will be able to accelerate vertically.
Why is thrust to weight ratio the inverse of lift-to-drag ratio?
In cruising flight, the thrust-to-weight ratio of an aircraft is the inverse of the lift-to-drag ratio because thrust is the inverse of drag, and weight is the inverse of lift.
