What is the difference between turbofan and turbojet?
Unlike a turbojet that sucks in all the air inside the engine, a turbofan engine sports a large fan at the front which sucks in most of the airflow around the outside of the engine. This makes the engine quieter and more thrust at low speeds. A majority of all the airliners are powered by this engine.
What is the advantage of diesel fuel?
Diesels get great mileage. They typically deliver 25 to 30 percent better fuel economy than similarly performing gasoline engines. Diesel fuel is one of the most efficient and energy dense fuels available today. Because it contains more usable energy than gasoline, it delivers better fuel economy.
What is the difference between aviation fuel and diesel?
Jet-A is a relatively high sulfur fuel, diesel is low sulfur and EPA requirements are getting more stringent about sulfur in diesel every year. Jet-A is “dry.” Diesel is made in such a way, or additives are mixed in, to lubricate the injector system of a diesel engine. 3. Jet-A is closer to kerosene and Diesel #1.
What are some advantages and disadvantages of diesel engines in aircraft?
Their main advantages are their excellent specific fuel consumption, the reduced flammability and somewhat higher density of their fuel, but these have been outweighed by a combination of inherent disadvantages compared to gasoline-fueled or turboprop engines.
