Which type of engine is used in jet engine?

Jet engines use gas turbine engines, which are also known as combustion turbines. It is a type of internal combustion engine that converts the fuel’s chemical energy into mechanical energy. The basic principle behind the functioning of a gas turbine engine is to intake air and mix it with fuel in the combustion chamber. The resulting combustion drives the turbine, which converts the kinetic energy into mechanical energy to produce thrust.

For more information on gas turbine engines and jet engines, you can visit websites such as Aerospace Engineering or Pratt & Whitney. These websites provide detailed information and diagrams about the functioning and components of jet engines.

How big can an RC jet engine be?

RC jet engines come in a range of sizes, from tiny micro-turbines to larger engines that can weigh several pounds. Some factors that can influence the size of an RC jet engine include cost, weight, and power output. Here are some examples of different-sized RC jet engines:

Size Description
Micro-turbine The smallest type of RC jet engine, often used in small-scale models
Small turbine Typically used in high-performance model jets and can achieve speeds of 100+ mph
Medium turbine Used in larger model jets with wingspans of 1.5m or more
Large turbine Commonly used in 1/4 or 1/3-scale models and can weigh upwards of 15kg

It’s worth noting that some hobbyists have taken on the challenge of building their own custom engines, pushing the boundaries of what is possible in terms of size and performance. While this can result in impressive feats of engineering, it also requires a large investment of time and resources. There are a variety of resources available online for those interested in building their own RC jet engines, including forums and instructional videos.
However, if you are looking for the largest RC jet engine available commercially, you can check out the Jetcat P550-PRO Turbine Engine, produced by Jetcat. This engine boasts a power output of 127 pounds of thrust, making it one of the most powerful RC jet engines on the market.

What kind of engines are in RC jets?

There are two common types of engines found in RC (remote control) jets:

  • Turbine engines: These are miniature versions of the same type of engines that power commercial jets. They use a combustion process to heat air and propel the plane forward. Turbine engines are favored for their realistic sound and high speed capabilities.
  • Electric ducted fan (EDF) engines: These engines use an electric motor to power a fan that draws in air and propels the plane forward. EDF engines tend to be quieter and easier to operate than turbine engines, but they generally lack the speed and power of their counterparts.

There are many resources available online for RC jet enthusiasts, including websites such as and that offer forums, reviews and advice on equipment and engines. Additionally, manufacturers such as Horizon Hobby and Motion RC sell a wide variety of RC jets and engine options.

The largest RC jet engine in the world

The current record holder for the largest RC jet engine in the world is the Frank Ohle’s MTT Turbine Superbike engine. Here are some of the engine’s impressive specifications:

  • Weighs 264 pounds (120 kg)
  • Produces 420 horsepower
  • Measures nearly 5 feet in length (1.5 meters)
  • Features a turbine from a helicopter engine

The MTT Turbine Superbike engine was originally built for use in a motorcycle but has since been adapted for use in RC airplanes. While it may seem unwieldy due to its size, this engine is actually capable of propelling an RC airplane to speeds of up to 325 mph (523 km/h). The massive engine makes for a striking sight when installed in an RC airplane, and videos of it in action have garnered millions of views online.

Interested hobbyists may be curious about the cost of the MTT Turbine Superbike engine, but with only a few in existence, there is no definitive answer.

How does an RC jet engine work?

An RC jet engine works by compressing air with a turbine, mixing it with fuel, and igniting it in a combustion chamber. The resulting hot, expanding gases push out the back of the engine, providing thrust. Here are some key points about how an RC jet engine works:

– The turbine compresses incoming air, which is then mixed with fuel and ignited in the combustion chamber.
– The hot gases produced by combustion expand rapidly, pushing out through the back of the engine.
– The process of combustion and expansion produces a lot of noise and heat, which must be managed carefully in order to prevent damage to the engine or surrounding components.
– RC jet engines typically use either kerosene or propane as fuel, and require specialized equipment and expertise to operate safely.
– Some popular brands of RC jet engines include JetCat, KingTech, and Turbine Solutions.
