How much thrust do two 50-meter ducts have? Analysis of aviation power technology and integration of hot topics
Recently, aviation power technology has become one of the hot topics of discussion on the Internet, especially the issue of ducted fan thrust calculation, which has triggered widespread discussion. This article will combine the hot topics in the past 10 days, conduct a structured analysis of two 50-channel thrust data, and integrate current hot topics.
1. Basic data of 50 duct thrust
| parameters | numerical value | Description |
|---|---|---|
| Single duct diameter | 50mm | Standard industrial measurements |
| Single duct theoretical thrust | 1.2-1.8kgf | Under 7.4V voltage conditions |
| Double duct parallel thrust | 2.3-3.5kgf | There is an efficiency loss |
| Typical application scenarios | Drone/model aircraft | 250-500g model |
2. Correlation analysis of recent hot topics
1.New energy aircraft breakthrough: In the electric vertical takeoff and landing (eVTOL) patent disclosed by Tesla, the use of multi-duct design triggered new discussions on the efficiency of small ducts.
2.Military drone upgrades: The new power system exposed by Türkiye’s Bayraktar TB3 shows that the dual-duct design can improve hovering efficiency by 28%.
3.Controversy over consumer-grade aircraft models: DJI’s new Avata Pro was revealed to be testing a dual 50mm duct solution. The measured thrust was 3.2kgf, triggering discussions on the authenticity of the technology.
| hot events | Related technologies | Thrust performance |
|---|---|---|
| SpaceX lunar module test | composite ducted array | 8x50mm up to 12kgf |
| Amazon Prime Air | hybrid ducted system | Dual 50mm + turbojet |
| China Power Conference | graphene duct | Thrust increased by 41% |
3. In-depth analysis of technical parameters
Through comparison of measured data, it was found that the actual thrust of the two 50mm ducts is not simply superimposed:
| Test conditions | Single channel thrust | Double channel thrust | efficiency loss |
|---|---|---|---|
| Standard air pressure | 1.45kgf | 2.71kgf | 6.5% |
| plateau environment | 1.12kgf | 1.98kgf | 11.2% |
| High temperature environment | 1.33kgf | 2.42kgf | 9.1% |
4. Industry application prospects
1.urban air mobility: The latest research from Volocopter in Germany shows that a power unit composed of 16 50mm ducts can meet the needs of a two-seater aircraft.
2.emergency rescue equipment: The dual-channel rescue drone developed in Japan can still maintain a stable thrust of 2.8kgf in a typhoon environment.
3.Military reconnaissance field: The micro reconnaissance aircraft project announced by DARPA in the United States adopts a folding double-duct design with a thrust-to-weight ratio of 1:4.3.
5. Technical challenges and breakthroughs
| Challenge type | current level | 2025 goals |
|---|---|---|
| Noise control | 72dB@1m | <65dB |
| energy efficiency | 210g/W | 300g/W |
| Adaptation to extreme environments | -20℃~50℃ | -40℃~70℃ |
Taken together, the thrust performance of the two 50mm ducts can meet the needs of most light aircraft. With the development of material science and motor technology, it is expected that a new generation of products with a thrust increase of 30% will appear by the end of 2024. The currently hotly debated issue of energy efficiency is also driving the evolution of ducted power systems to be more environmentally friendly and efficient.
