A “pound of thrust” is equal to a force able to accelerate 1 pound of material 32 feet per second per second (32 feet per second per second happens to be equivalent to the acceleration provided by gravity).
How many pounds of thrust does a 747 have?
| Boeing 747 100 | Maximum Takeoff Weight (MTOW) 735,000 lbs 333,400 Kg | Maximum Fuel Capacity 48,445 US Gal. 183,380 Litres | Engines and Thrust Pratt & Whitney JT9D-7A Thrust 46,500 lb (20,925 kg) Rolls-Royce RB211-524B2 Thrust 50,100 lb (22,545 kg) GE CF6-45A2 Thrust 46,500 lb (20,925 kg) | Boeing 747 100 |

How many horsepower is a pound of thrust?
Using this concept, at an airspeed of 375 mph, one pound thrust would equal one horsepower .
What is meant by thrust force?
Thrust is the force which moves an aircraft through the air . ... Thrust is generated most often through the reaction of accelerating a mass of gas. Since thrust is a force, it is a vector quantity having both a magnitude and a direction.
How many pounds of thrust does a jet engine produce?
“Todays jet engines commonly develop 9,900 pounds of thrust or more.”
How many HP is 55 lbs of thrust?
| Pounds of Thrust (lbs) Amps Horsepower | 40/45 42 0.5 | 50/55 50 0.6 | 70 42 1.01 | 80 56 1.35 |

How much horsepower is 7.5 million pounds of thrust?
Saturn V engines capable of 7.5 Million pounds of thrust. The most powerful rocket ever made! 160,000,000 HP | Apollo space program, Space race, Space exploration.
Can a 747 take off with 2 engines?
A 747 cannot takeoff with just two engines because the time it would take to pick up enough speed would have it half way there, but once its in the air, they’ll keep it moving. 2. If these two engines were on the same side, it would take everything but the galley sink to keep the airplane from turning.
Is Boeing 777 bigger than 747?
The 777 is both longer in length than the 747 , as well as having a longer wingspan. No surprisingly, the 777 is shorter than the 747, however, it isn’t as short as you’d expect, it’s only three feet shorter.
How much is a gallon of jet fuel?
170.8 Cents (US dollars) per Gallon.
What is difference between thrust and force?
| Force Thrust | A force could be a push or pull on an object. Thrust is the force that pushes aircraft forward or upwards. |

What is the difference between thrust and weight?
Weight is the force of gravity . It acts in a downward direction—toward the center of the Earth. ... Thrust is the force that propels a flying machine in the direction of motion. Engines produce thrust.
What is difference between pressure and thrust?
(1) Force acting perpendicular to the surface of an object is known as Thrust. (1) Thrust acting per unit area is known as pressure.
How much thrust does it take to lift a human?
Yes, lift is nothing but the force in the upward direction. So to keep a 150 pound person aloft, you need a lift of 150 pounds (150 pound-force).
How much thrust does it take to lift a pound?
Thrust is measured in “pounds of thrust” in the U.S. and in newtons in the metric system. 4.45 newtons of thrust equals 1 pound of thrust. A pound of thrust is how much thrust it would take to keep a one-pound object unmoving against the force of gravity on earth.
How efficient is jet engine?
Motor thermodynamic efficiency of commercial aircraft engines has improved from about 30 percent to over 50 percent over the past 50 years, as shown in Figure 3.3. Most commercial airline engines are designed to maximize efficiency at cruise, since that is where most fuel is burned.
