How do you calculate specific thrust?
Specific thrust is the thrust per unit air mass flowrate of a jet engine (e.g. turbojet, turbofan, etc.) and can be calculated by the ratio of net thrust/total intake airflow.
What does CFM stand for in jet engines?
product line
CFM is not an acronym, so it doesn’t stand for anything. The company (CFM), and product line (CFM56), got their names by a combination of the two parent companies’ commercial engine designations: GE’s CF6 and Snecma’s M56.
How much horsepower does a GE90 have?
Bangalore Aviation points out that a single GE90-115B engine puts out over 110,000 horsepower, or more than twice the design output of all the Titanic’s steam engines. And that power is obviously hooked up to a much smaller vehicle.
How much does a CFM56 engine weight?

| Model | Thrust | Dry weight |
|---|---|---|
| CFM56-5B3 | 33,000 lbf (150 kN) | 5,250 lb (2,380 kg) |
| CFM56-5B4 | 27,000 lbf (120 kN) | 5,250 lb (2,380 kg) |

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?
Calculation. The thrust-to-weight ratio is calculated by dividing the thrust (in SI units – in newtons) by the weight (in newtons) of the engine or vehicle. Note that the thrust can also be measured in pound-force (lbf), provided the weight is measured in pounds (lb).
How do you calculate thrust on a propeller?
- Most general aviation or private airplanes are powered by internal combustion engines which turn propellers to generate thrust.
- F = delta p * A.
- force = (force/area) * area.
- pt0 = p0 + .5 * r * V0 ^2.
- pte = p0 + .5 * r * Ve ^2.
- delta p = pte – pt0.
- delta p = .5 * r * [Ve ^2 – V0 ^2]
- F = .5 * r * A * [Ve ^2 – V0 ^2]
How big was the Titanic engine?
The two reciprocating engines were each 63 feet (19 m) long and weighed 720 tons, with their bedplates contributing a further 195 tons. They were powered by steam produced in 29 boilers, 24 of which were double-ended and five single-ended, which contained a total of 159 furnaces.
