Thrust Performance Guide
| Engine Type | Typical Thrust (kN) | Specific Impulse (s) |
|---|---|---|
| Turbofan (Jet) | 50–400 | 3000–8000 |
| Turbojet (Jet) | 10–100 | 1000–2000 |
| Solid Rocket | 100–5000 | 250–300 |
| Liquid Rocket | 500–7000 | 300–450 |
Note: Results are theoretical based on input parameters. Actual thrust depends on engine design, altitude, and conditions. Consult aerospace engineers for precise performance analysis.
Thrust Calculator – Calculate Propulsion Force Instantly
Whether you’re working with drones, rockets, jets, or RC planes, our Thrust Calculator gives you a fast, physics-based estimate of how much force your system produces. No formulas, no confusion — just results.
What is a Thrust Calculator?
A Thrust Calculator helps determine the force of propulsion generated by a system like a propeller, jet engine, or rocket. It uses scientific formulas based on Newton’s Third Law to calculate the thrust (in Newtons or pounds-force) from velocity, air density, and mass flow.
For propellers, the formula often used is:Thrust = ½ × ρ × A × (Ve² – Vo²)
Where:
- ρ = Air Density
- A = Propeller Disc Area
- Ve = Exit Velocity
- Vo = Entry Velocity
This tool simplifies that into easy input fields and instant answers.
