== Description ==
<div style="width:auto; overflow:auto; border-radius:10px; background-color:white;"><p style="margin:5px 0px 5px 10px;"><i>"Inefficient but very powerful, the [[Pressure Fed Gas Engine]] moves gas from each of its two inputs based on the pressure of the input pipes. Control the mixing ratio of fuel by tweaking the input pressures to a target 2:1 mix of [[Volatiles|Liquid Volatiles]] to [[Oxygen|Liquid Oxygen]] gas. Chilling propellant gasses or using [[Nitrous_Oxide|Liquid Nitrous Oxide]] as an oxidizer will result in even higher thrust output."</i><br><b>- Stationpedia</b></p></div>

== Comparison ==
{{:Rocket_Engines}}

== Controversy==
This engine is controversially discussed among stationeers as possibly beeing the best choise of engine, but it depends on the use case. If using [[Liquid Nitrous Oxide]] as an oxydizer, it will most likely liquify in the tanks andor pipes and make your rocket go boom.

== Usage ==
To make the rocket work, use 2 [[Pipe Volume Pump|Volume Pumps]], 2 [[Pipe Analyzer|Pipe Analyzers]] and a IC10 Script to keep the Pressure up. Maybe don't build this rocket if it's your first one.
The ideal pressure of the intake pipes is not a fixed number; it depends on the size and weight of your rocket and needs to be determined either mathematically or by trial and error.<br>
<br>
== Control ==
Setup that proves to work nicely:<br>
define ATMOSMODEVOLPRESSURE 10000

define ATMOSMODEOXYPRESSURE 5000

define FULLMODEVOLPRESSURE 54000

define FULLMODEOXYPRESSURE 27000

define LOWTHROTTLETHRESHOLD 60 # the rocket is possibly landing when Throttle is lower that

=== Define Constants and Variables: ===
<br>
<big>Pressure Settings:</big> Determine and define the pressure values for both atmosphere and full mode. These will be used to control the pressure of the gases in the system.
<br>
<big>Engine Parameters:</big> Identify key parameters such as throttle thresholds and engine hash identifiers.<br><br>
Initialize Components:<br>
<big>Enable Components:</big> Turn on the necessary components like Volume Pumps and Pipe Analyzers to ensure they are functioning correctly.<br>
<big>Set Up Variables:</big> Initialize variables for tracking current values like thrust-to-weight ratio and throttle.
<br>
<br>
=== Monitor Engine State ===
<br>
<big>Measure Thrust-to-Weight Ratio:</big> Continuously check the current thrust-to-weight ratio to determine the operating state of the rocket.<br>
<big>Throttle Levels</big> Monitor the current throttle level to determine if the rocket is under high or low throttle conditions.<br>
=== Throttle ===
<br>
<big>Low Throttle Condition</big> If the throttle is below a certain threshold, this usually indicates the rocket might be landing or in a low-power state. Adjust the pressure settings accordingly.<br>

<big>High Throttle Condition</big> For high throttle, maintain or adjust the pressure settings to ensure optimal performance and efficiency.
<br>
=== Pressure Adjustment Logic===
<br>
<big>Atmosphere Mode</big> Set the pressure values for gas inputs to match the atmospheric conditions. This involves checking if the pressure is too high or too low and adjusting the volume pumps accordingly.
<br>
<big>Full Mode</big> When the rocket is in full power mode (e.g., during Takeoff or possibly landing), adjust the pressures to higher values to optimize thrust.
<br>
<br>
=== Control Loop ===
<br>
<big>Continuous Monitoring</big> The script should continuously loop, checking and adjusting the pressure settings based on the current state of the rocket. This ensures the rocket operates efficiently throughout its journey.
<br>
=== Handling Pressure Adjustments ===
<br>
<big>Adjust Pumps:</big> Depending on the current pressure readings, activate or deactivate pumps and set their volumes to reach the desired pressure levels.<br>

<big>Update Settings:</big> Make real-time adjustments to the pump settings to maintain the appropriate pressure levels for both atmosphere and space conditions.<br>
