An aircraft engine, also known as an aneroid engine, is the primary power unit of any aircraft propulsion system. In recent years, many smaller UAVs have employed electric motors as their primary propulsion system. This is because an electric aircraft engine is more efficient and is capable of delivering higher power levels than any other conventional gasoline engine.
For example, a propulsive thrust system using an electric aircraft engine can be capable of generating up to seven times more thrust than a comparable gas engine. This is because electric engines have less friction compared to an engine that utilizes the use of gas. An electric engine also has a long life cycle, which means that the engine will last a very long time when operating with minimal maintenance.
However, the advantages of using an electric engine are not just limited to the ability to operate without friction. For one thing, there is considerably less noise produced by electric engines compared to a gas engine. Because of this, an electric engine is much quieter compared to gas engines. Additionally, a gas engine requires fuel to be burned to maintain its temperature, whereas an electric engine only needs electrical energy. This means that an electric engine can run for a much longer period without requiring a refill.
In addition to being quieter, the biggest advantage of using an electric aircraft engine is that a fuel consumption problem that occurs with a gas engine can be solved by simply replacing the fuel source. This is not possible with an electric engine. As previously mentioned, an electric aircraft engine requires no fuel to operate at its best. This means that an electric aircraft engine is very easy to maintain. Unlike gas engines, electric engines do not require any oil changes.
There are many other advantages to electric aircraft engines, but there are some disadvantages as well. These include:
The main reason why gasoline engines became so popular was that they were less expensive to operate compared to fuel-burning engines. However, these engines proved to be less efficient than an electric engine. This is because they used fuel to generate power instead of electricity, which is better able to generate high thrust. in the air because it is more efficient and does not consume so much fuel.
Gasoline engines also produce less horsepower than electric engines. Because of this, they are used on smaller aircraft and are therefore not as effective in the air as larger engines. Because of their size, they are not able to deliver as much thrust as their larger counterparts.
When an engine is used in conjunction with a fuel-burning engine, it may experience an increase in the noise produced. For this reason, many anaerobic aircraft, such as helicopters, use more powerful engines to improve their thrust performance. Because of this, they are designed to use engines that produce less exhaust noise compared to their counterparts.
Pros and Cons
Electric engines can be a little harder to start because of the need to use a power switch to make the ignition switch for a battery. The disadvantage is that these switches are typically very hard to find and therefore may take a while to start. Besides, if you need to start your engine, you will have to run up a short of batteries to start it.
Gasoline engines tend to run at a higher operating temperature than engines powered by electricity. Because of this, they are also a bit harder to start and may need a battery to start them. A drawback of this is that a gas engine powered by electricity tends to require more fuel to get started and can run out of fuel before you can get it started. This can lead to less performance and greater risks of accidents.
Fuel costs can also be a problem for some applications. Because gasoline engines use gasoline, they must be refilled, which costs money. An alternative to using gas is to use diesel or propane, which costs considerably more to use than gasoline. It is also difficult to change the fuel tank to refill it since they are much larger. This means that there is a limit to how much fuel can be stored, which can affect how long the engine will run.
In summary, there are some advantages to using an electric aircraft engine to create a more economical aeroplane. While these engines are not as powerful as their gas counterparts, they are much easier to start, run longer and cost less money to operate. However, the biggest disadvantage is that they are louder and can cost more to maintain.
