What Is the Difference Between a Single-Engine and Multi-Engine Helicopter?
As the most common type of rotary-wing aircraft, helicopters come in a large variety of designs to suit different environments and applications. One major way to differentiate the types is by the number of engines they employ to run the main rotor blades and other powered components. As a key safety feature, using multiple engines is often required for flying over certain areas; however, one should not discount the benefits of a single-engine design. To learn more about the key differences between these two varieties, read on as we discuss some major considerations.
If you are referring to the different number of engines for various helicopters, you can use the terms “single-engine” and “multi-engine.” Within this distinction, multi-engine helicopters are those that use two or more engines to power their main rotor blades. As a result, they offer a higher level of safety due to their redundancy. More specifically, the addition of one or more engines means that a pilot can keep their helicopter airborne even if one (or more) of the engines fails, allowing for a safe landing. This often means that they are preferred in areas with high population density where it may be deemed too risky to rely on a single engine.
That said, single-engine helicopters are not doomed to catastrophe in the case of engine failure. While not as simple as shifting to a different engine, pilots of single-engine helicopters can still use the existing rotation of the blades to safely descend without power. Nevertheless, multi-engine helicopters also offer increased power and performance capabilities, making them ideal for high-performance applications such as firefighting or military operations. Single-engine helicopters, on the other hand, are lighter and more agile, making them better suited for applications requiring precision and maneuverability, such as aerial filming or photography. They are also more cost-effective to purchase and maintain, proving to be a popular choice for applications that do not require the added level of safety provided by multi-engine helicopters.
Understanding the differences between single-engine and multi-engine helicopters can help you make an informed decision when choosing which type to use for a specific application. In addition to cost, it is important to consider the level of safety required, the performance capabilities needed, and the level of maneuverability necessary for the task at hand. In addition, no matter the engine setup, it is always important to source engine components that have met the high standards expected of aviation parts.
