As an expert in the field of aviation, I can provide you with a detailed answer regarding the fuel consumption of helicopters. Helicopters are a marvel of engineering, and their fuel consumption can vary greatly depending on a number of factors including the type of engine, the size and weight of the helicopter, the altitude at which they are flying, and the specific model of the helicopter.
Step 1: English Answer
Helicopters are unique in that they use a rotary wing system to achieve lift and propulsion, unlike fixed-wing aircraft which rely on forward motion to generate lift. This fundamental difference in design leads to different fuel consumption patterns compared to traditional airplanes.
### Types of Helicopters and Engines
There are two main types of helicopter engines: piston engines and turbine engines. Piston engines are similar to those found in cars and small aircraft, while turbine engines are more akin to jet engines and are used in larger, more powerful helicopters.
### Piston Engine Helicopters
Piston engine helicopters are typically smaller and used for training or recreational purposes. They operate on a reciprocating engine, much like a car engine, and are known for their lower acquisition and maintenance costs. However, they are also less fuel-efficient compared to turbine engines.
According to the information provided, a small two-seat training helicopter with a piston engine typically burns about 9 to 16 gallons per hour. This range can vary based on the specific model of the helicopter, the weight it is carrying, and the conditions under which it is flying.
### Turbine Engine Helicopters
Turbine engine helicopters are larger and more powerful, often used for commercial transport, military operations, and emergency services. They are more complex and expensive to operate but offer greater speed, range, and payload capacity.
The same source mentions that a larger five-seat turbine helicopter typically burns about 25 to 30 gallons per hour. However, this figure can be deceptively simple. Turbine helicopters have a wide range of fuel consumption rates depending on the specific model and its design. For instance, a high-performance military helicopter might consume significantly more fuel than a civilian utility helicopter of the same size.
### Factors Affecting Fuel Consumption
Several factors can influence the fuel consumption of a helicopter:
1. Engine Efficiency: The efficiency of the engine directly affects fuel burn. Modern engines are designed to be more fuel-efficient.
2. Helicopter Size and Weight: Larger and heavier helicopters require more power to lift off and stay aloft, which translates to higher fuel consumption.
3. Altitude: Flying at higher altitudes requires more power, which increases fuel consumption.
4. Climate and Weather: Hot temperatures and high humidity can reduce engine efficiency, leading to higher fuel use.
5. Flight Profile: Frequent take-offs and landings, as well as hovering, are more fuel-intensive than cruising at a constant altitude.
6. Maintenance and Condition: Well-maintained helicopters with properly tuned engines will generally consume less fuel.
### Fuel Types
Helicopters, like other aircraft, use a variety of fuels. The reference to "Jet A" fuel is accurate for some turbine helicopters. Jet A is a type of aviation fuel similar to kerosene but with additional specifications to ensure safety and performance. It is used widely for turbine engines due to its reliability and availability.
### Conclusion
In conclusion, the fuel consumption of a helicopter can vary widely based on numerous factors. While the figures provided offer a general idea, it's important to consider the specific helicopter model, its engine type, and the operational conditions when assessing fuel consumption. For precise data, consulting the helicopter's flight manual or speaking with a manufacturer's representative would be the best approach.

Turbines use a type of fuel known as "Jet A", which is simillar to very clean Kerosene. A small two seat training helicopter with a piston engine typically burns about 9 to 16 gallons per hour. A larger five seat turbine helicopter typically burns about 25 to 30 gallons per hour.
