Thrust Limiting

Learn how to effectively manage and limit thrust in Kerbal Space Program to ensure stable and controlled ascents and maneuvers. This guide covers essential techniques for KSP.

The Kerbal Space Program Wiki is dedicated to providing comprehensive information about Squad's spaceflight simulator. This section focuses on the crucial aspect of thrust limiting.

What is Thrust Limiting?

Thrust limiting is a technique used in Kerbal Space Program to control the maximum output of a rocket engine. By adjusting the thrust limiter, players can reduce the force generated by an engine, which is essential for managing acceleration, preventing structural failure, and achieving stable flight, especially with powerful engines or lighter craft.

Why is Thrust Limiting Important?

• Stability: Prevents rockets from becoming unstable and flipping due to excessive thrust, particularly during atmospheric ascent.
• Control: Allows for finer control over maneuvers, especially when using high-thrust engines.
• Structural Integrity: Reduces stress on rocket parts, preventing them from breaking apart under high G-forces.
• Fuel Efficiency: Can help in optimizing fuel consumption for certain flight profiles.
• Landing: Crucial for soft landings on celestial bodies by allowing precise control over descent speed.

How to Use Thrust Limiting:

In the VAB (Vehicle Assembly Building) or SPH (Spaceplane Hangar), select an engine. In the part's action menu, you will find a slider or input field labeled 'Thrust Limiter'. This can be adjusted from 0% to 100%. Setting it to a lower percentage will reduce the engine's maximum thrust output.

When to Use Thrust Limiting:

• Early stages of ascent when the rocket is most susceptible to aerodynamic forces.
• When using very powerful engines on light or small rockets.
• During precise orbital maneuvers where overshooting can be detrimental.
• For controlled landings, especially on low-gravity bodies or when using large engines.
