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 (kg) Power (kW) Cost (₠) Volume (m³)
-1 Propellor Thrust ÷ 16.5 + 8 1.5 × Thrust Mass × 10
0 Ducted Fan Thrust ÷ 16.5 + 8 2 × Thrust Mass × 10 Mass ÷ 150
0 Helicopter Thrust ÷ 6.5 + 8 5 × Thrust Mass × 20 Mass ÷ 75

Mass and Power are per Newton of thrust. Helicopter blades also produce 1kg of static thrust per Newton.
