Altitude simulation

Definition

Altitude simulation is the process of recreating the atmospheric conditions experienced at high altitudes in a controlled environment, typically using specialized test facilities or equipment. This method is essential for evaluating the performance and reliability of propulsion systems under varying pressure and temperature conditions that closely mimic those found at different altitudes, ensuring that the systems function effectively in real-world scenarios.

5 Must Know Facts For Your Next Test

1. Altitude simulation helps to replicate conditions like reduced oxygen levels and lower air pressure, allowing engineers to test how propulsion systems react in such environments.
