Come melt your face off with our latest jet engine addition to SimpleRockets 2. Put the throttle lever to the metal, and fulfill your need for speed. Full release notes can be found here.

Here's a new trailer showing them off:

We really went all out on these. I hit the textbooks and learned about the thermodynamics of jet engines, (which are fascinating, btw) and Kevin created detailed, modular jet engine models. In the end, we have a highly procedural jet engine part that can be used to create anything from old-style turbojets to new low-bypass military turbofans to high-bypass civilian airliner engines.

You can also tweak several visual aspects of the engine, including the shroud style, length, and curvature. Cycle through the available nozzle styles, fan styles, and inlet cones. Here's a quick GIF showing some of the features:

You can tweak the size, bypass ratio, compression ratio, and afterburner and see how it affects the performance. The designer has some extra tools to help analyze performance at different altitudes and airspeeds:

Jet engines need air to breathe, so the new inlet part helps to make sure your jet engines are getting enough air. If you connect an inlet directly to a jet engine, it will only provide air to that engine. If you connect an inlet somewhere else on your craft, it will provide air to any jet engines that don't have sufficient airflow. If you're curious about how your engines are doing, you can click on them during flight and check their Inlet Efficiency to ensure they are getting enough air.

Of course, the fun doesn't stop there. Kevin built two new stock airplanes to show off the new jet engines.

They are a blast to fly and it's fun to watch the new jet engines in action. Don't forget to turn on the new heat distortion particle effects for maximum enjoyment.

    @AndrewGarrison - maybe "overall pressure ratio" could be added to the analysis panel as an output.

    6.4 years ago
  • Profile image

    @swope compression ratio is the compressor's exit pressure divided by the compressor input pressure. The overall pressure is 1.5 * CompressionRatio because the bypass fan has a fan pressure ratio of 1.5.

    @czenon1 @mjdfx150529 yep, I agree we need better landing gear. @HellFireKoder is working on those.

    6.4 years ago
  • Profile image

    @CRJ900Pilot lol, yep we put procedural jet engines in the rocket game instead of the plane game. Before this update, SP players mostly wanted tank parts in the plane game. Never judge a book by its cover! And when it comes to Jundroo games, never judge a game by its name...

    @Gameboy21 these are just marketing techniques to get you to buy or upgrade to SimpleRockets2
    Or the devs really enjoyed their selves making this one

    Is "compression ratio" in the engine settings synonymous with "overall pressure ratio" or is it meant to be only input to the exit of the compressor?

    Hey @AndrewGarrison can you add this feature to SimplePlanes, custom jet engines like this would help a ton for fighter aircraft.

    +2 6.4 years ago
  • Profile image

    I figured out a problem with my plane, the electric motor on my plane had really odd effects:
    Braking caused the craft to accelerate quickly.
    After around 300 m/s the craft will also begin to accelerate up to 1000 m/s

    Not sure how this is happening, but removing the propeller fixed it. Can we get normal props like in simple planes next?
