What do helicopters use as fuel?
As an important tool for modern air transportation, helicopter fuel selection is directly related to flight performance, economy and environmental protection. This article will combine the hot topics and hot content on the Internet in the past 10 days, analyze the fuel types and characteristics commonly used in helicopters, and display relevant information through structured data.
1. Commonly used fuel types for helicopters
Helicopters mainly use the following three types of fuel: aviation kerosene (Jet A/A-1), aviation gasoline (Avgas) and biofuel. Here's how they compare:
| Fuel type | Main ingredients | Applicable models | Environmental protection |
|---|---|---|---|
| Aviation kerosene (Jet A/A-1) | hydrocarbons | turbine engine helicopter | Medium, high carbon emissions |
| Avgas | high octane gasoline | Piston engine helicopter | Poor, lead contamination |
| biofuels | Plant or algae extract | Some new helicopters | Excellent, renewable |
2. Factors in fuel selection
Helicopter fuel selection is affected by many factors, including engine type, flight mission, cost and environmental requirements. The following are the key points mentioned in popular discussions in the past 10 days:
1.Engine type: Turbine engine helicopters usually use aviation kerosene, while piston engine helicopters use aviation gasoline.
2.Environmental trends: As the world pays attention to carbon emissions, the research and development and application of biofuels have become a hot topic. For example, Airbus recently announced that it will test helicopters powered by 100% sustainable aviation fuel (SAF).
3.Economy: The price of aviation kerosene is relatively stable, while the cost of biofuel is high, but it may decrease due to policy support in the long run.
3. Comparison of fuel performance
The following is the performance comparison data of the three fuels:
| Fuel type | Energy density (MJ/kg) | Freezing point (℃) | Flash point (℃) |
|---|---|---|---|
| Aviation kerosene (Jet A/A-1) | 43.5 | -40 | 38 |
| Avgas | 44.0 | -58 | -43 |
| biofuels | 42.0 | -50 | 30 |
4. Future development trends
According to recent hot discussions, the future development of helicopter fuel may focus on the following directions:
1.Sustainable aviation fuel (SAF): Several airlines are testing the application of SAF on helicopters to reduce carbon emissions.
2.electric helicopter: Although electric helicopters currently have limited endurance, advances in battery technology may change this situation.
3.hydrogen fuel: Hydrogen is being studied as a zero-emission fuel for future helicopters.
5. Conclusion
Helicopter fuel selection is a complex issue that requires balancing performance, economic and environmental needs. At present, aviation kerosene and aviation gasoline are still the mainstream, but the rise of biofuels and electric technology will gradually change this pattern. In the future, with the advancement of technology and the promotion of environmental protection policies, helicopter fuel will be more diversified and sustainable.
