Helicopters are versatile aircraft that can take off and land almost anywhere, but they are known to use a lot of fuel. The amount of fuel a helicopter uses depends on various factors, including the size, weight, type of helicopter, and engine type. Small piston-powered helicopters, which are commonly used for training and personal transportation, are more fuel-efficient than their larger turbine-powered counterparts. They typically burn between 5-20 gallons/19-76 liters of fuel per hour, while larger helicopters can use anywhere from 20 to several hundred gallons of fuel per hour. Additionally, hovering requires more fuel than cruising, impacting the overall fuel economy of helicopters.

Small piston-powered helicopters use 6-16 gallons of fuel per hour
The amount of fuel a helicopter uses depends on its size, weight, type, and engine type. Small piston-powered helicopters are quite fuel-efficient, burning fuel at a rate of 6-16 gallons per hour. This is because they are lighter and less powerful than turbine-powered helicopters. Piston engines are also more fuel-efficient than gas turbine engines, which burn fuel at a much higher rate. This makes small piston-powered helicopters a popular choice for training and private ownership.
Piston-powered helicopters are also cheaper to maintain and more fuel-efficient than their turbine counterparts. They are ideal for occasional flights and can usually seat up to three people. For this reason, they are often used for training, personal transportation, and sightseeing. Police forces also use piston-powered helicopters for general surveillance due to their high maneuverability.
The fuel efficiency of helicopters is impacted by their ability to hover and take off and land in tight spaces. However, hovering uses more fuel than cruising, as the main rotor has to create all the lift to keep the helicopter in the air. Helicopters also fly at slower speeds than airplanes, which further affects their fuel economy.
The type of fuel used by helicopters also depends on the type of engine. Most small planes and helicopters use aviation gasoline (AvGas), which is a high-octane fuel with a higher refinement that provides a cleaner burn. Jet fuel is typically used in helicopters with gas turbine engines, especially those with higher horsepower ratings.

Turbine-powered helicopters use 20-1100 gallons of fuel per hour
The amount of fuel a helicopter uses depends on several factors, including the size, weight, type of helicopter, and engine type. For example, piston-powered helicopters are typically smaller and have lower fuel consumption than turbine-powered helicopters. Piston engines burn fuel at a lower rate than turbine engines, making them more fuel-efficient.
The fuel efficiency of turbine-powered helicopters is lower than that of piston-powered helicopters. Turbine engines burn fuel at a much higher rate, resulting in increased fuel costs. This is a significant consideration when choosing between piston and turbine-powered helicopters.
The type of fuel used in helicopters also varies. Aviation turbine fuel, commonly known as jet fuel, is used in helicopters with gas turbine engines. Jet fuel is a kerosene-based fuel with two main types: Jet-A and Jet-A1. Jet-A1 is an improved version that can be used in colder temperatures. On the other hand, smaller helicopters and those used for training or private ownership often have piston engines and use aviation gasoline (AvGas). AvGas has a higher octane rating and is typically dyed to ensure the correct fuel is used.
In summary, turbine-powered helicopters have higher fuel consumption, burning 20-1100 gallons of fuel per hour, compared to piston-powered helicopters, which are more fuel-efficient. The choice between the two depends on factors such as intended use, passenger capacity, and operating costs, with fuel efficiency and fuel type playing a significant role in the decision-making process.

Jet fuel and aviation gasoline are two types of helicopter fuel
The amount of fuel a small helicopter uses depends on its size, weight, and type, as well as its engine type. Small piston-powered helicopters normally use between 5-16 gallons of fuel per hour, while larger turbine-powered helicopters can use anywhere between 20 to several hundred gallons of fuel per hour.
Helicopters use a lot more fuel than airplanes because their rotors are responsible for creating all the lift. The rotating rotor blades of a helicopter also cause a lot of drag when the helicopter cruises at high speed. The tail rotor also uses some fuel to ensure stable flight.
Aviation gasoline, also known as AvGas, is a high-octane gasoline fuel with a higher refinement, providing a cleaner and filtered fuel. It is used in most small planes and piston-powered helicopters in North America and Western Europe. The most common grade of AvGas is 100LL, which contains three times the amount of tetraethyl lead per litre than car gasoline to prevent detonations during combustion that could cause piston engine failure.

Fuel economy is better in piston-powered helicopters
The amount of fuel a helicopter uses depends on several factors, including its size, weight, type, and engine. Generally, helicopters are known for consuming a lot of fuel, especially when hovering, as their rotors are responsible for creating all the lift.
However, when it comes to fuel economy, piston-powered helicopters have an advantage over their turbine-powered counterparts. Piston-equipped aircraft burn fuel at a lower rate, making them more fuel-efficient. For example, small piston engine helicopters burn fuel at a rate of 5-20 gallons (19-76 liters) per hour, while larger turbine-powered helicopters can burn 25-1100 gallons (95-4165 liters) per hour. This difference in fuel consumption is primarily due to the higher fuel burn rate of gas turbines compared to piston engines.
The Robinson R-22, a small piston-powered helicopter, is often cited as one of the most fuel-efficient certified single-engine helicopters. It can carry barely two adults and burns around 10 gallons of fuel per hour, resulting in a cruising speed of over 80 knots.
Piston-powered helicopters, typically smaller in size, are popular for training, personal transportation, and sightseeing. They are also favoured for occasional flights and general surveillance by police due to their high maneuverability and lower fuel consumption. However, for transporting more than three people or operating in cold climates, turbine helicopters are more economical.
While piston engines offer better fuel economy, turbine engines have their advantages too. Turbine engines are more powerful, lighter relative to their output, more reliable, and perform better at high altitudes. Therefore, they are the preferred choice for medium-sized to large helicopters, especially military helicopters that require agility and the ability to carry a lot of equipment.

The price of helicopter fuel depends on the type
Another type of helicopter fuel is aviation gasoline, also known as AvGas. AvGas is a high-octane gasoline fuel with a higher refinement, resulting in a cleaner and filtered fuel. The most common type of AvGas is 100LL, which contains tetraethyl lead to prevent detonations during combustion that could cause piston engine failure. In 2020, the price of 100LL AvGas ranged from $4.60 to $5.34 per gallon in the lower 48 states.
The amount of fuel a helicopter uses also depends on its size, weight, and engine type. Small piston-powered helicopters typically use between 5-16 gallons of fuel per hour, while larger turbine-powered helicopters can use anywhere from 20 to several hundred gallons of fuel per hour. The helicopter's fuel efficiency is also affected by its rotors, which create lift and cause drag during cruising, resulting in higher fuel consumption compared to fixed-wing aircraft. Additionally, helicopters use more fuel when hovering than when in cruise or mid-flight.
