The indoor propene engines (IPP) are one of the most popular components for indoor aerial propane (AAP) systems, and they are also an integral part of many of the aerial propanes used for indoor air travel.
The most commonly used indoor propylene engines are the indoor skydive engine (ISPE) and the indoor propanol engine (IPSE).
IPSE and IPSE engines have a common design that allows for the use of the same main combustion chamber (CC), but they differ in their performance characteristics.
IPSE is a more powerful engine, but it is also less efficient.
IPSEs are also more expensive to build, requiring more time and expertise to design and build, and therefore require a larger quantity of cylinders to provide the same output power.
IPSEC also tends to be more complex than IPSE, requiring additional cylinder assemblies and a greater amount of fuel to be available to the engine.
IPSES are also considerably more expensive, requiring a higher quantity of pistons to provide power and a higher pressure, which also increases their cost.
These advantages and disadvantages are why the IPSE engine is not used in most indoor aerial applications, and IPSEs continue to be used in indoor aerial engines.
To provide an overview of how these engines work, we are going to review how they operate, and then we will discuss the advantages and drawbacks of each engine type.
