Air Propulsion
There are three ways of selecting your aerial propulsion system: By desired top speed, by engine power, or by mass.
To determine your aircraft's required thrust, you will first need to determine its Drag. This is easier than you might think: Take the aircraft's total Area, and divide by an amount based on the Streamlining, as found in the table below.
| Streamlining | |
|---|---|
| None | 1 |
| Mild | 2 |
| Moderate | 3 |
| Good | 5 |
| Excellent | 10 |
To find the thrust you need to meet your desired top speed, multiply the speed (in kph) by itself, then by your Drag. Divide this by 60. This gives you the thrust you need, in Newtons.
Airscrews
| TR | Type | Mass | Power | Cost | Volume (m³) |
|---|---|---|---|---|---|
| -1 | Propellor | Thrust ÷ 16.5 + 8 | 1.5 × Thrust | Mass × ₠9 | – |
| 0 | Ducted Fan | Thrust ÷ 16.5 + 8 | 2 × Thrust | Mass × ₠9 | Mass × 6.5 |
Mass and Power are per newton of thrust.
