As the designer of the Teching T700 turboshaft engine, I am deeply honored to be involved in the development of this revolutionary product. The design of this engine is inspired by the UH-60 Black Hawk combat helicopter, which is widely used in military operations around the world with its excellent performance, reliability and powerful power system. With the T700 engine, we hope to transform this top performance into a power system that model flying enthusiasts can experience.
Design Inspiration:
The Power Gene of the Black Hawk Combat Helicopter
Black Hawk Reliability and High Performance: The power system of the Black Hawk combat helicopter can maintain stable operation under extreme conditions, including bad weather, strong winds and high altitude environments. When designing the T700, I paid special attention to how to incorporate this high reliability and high thrust performance into the model engine. I believe that every flying enthusiast wants their aircraft to perform well in any environment, so I ensured that the engine can operate smoothly in various flight environments, whether it is aerial maneuvers or high-load flights.
High Thrust Output and Agility:
The Black Hawk's turboshaft engine provides stable thrust and can respond quickly to control commands. In the T700, I paid attention to this and ensured that the engine can provide enough thrust to support rapid acceleration and precise control. Whether it is a quick takeoff or an emergency maneuver, the T700 can meet the needs of flyers and allow them to experience more realistic flight control.
Tactics and Versatility:
The Black Hawk helicopter is designed to perform a variety of missions, including rescue, transportation, attack, etc. In the design of the T700, I also added a variety of functions to enable it to adapt to different types of flight missions. This makes the T700 not only a high-performance engine, but also can meet various flight needs, whether it is recreational flight or difficult flight challenges.
Technical Innovation and Design Highlights
Lightweight and High Durability: As a designer, I pay great attention to the balance between the weight and durability of the engine. The T700 uses lightweight materials while ensuring extremely high durability. This allows the aircraft to maintain higher maneuverability and extended flight time. I pay special attention to the durability of each component, using high-quality metal materials and advanced processing technology to ensure that the T700 still performs well under high-intensity flight.
Efficient noise reduction technology: Unlike other Teching turbofan engines, the T700 pays special attention to sound control. During the design process, I removed the sound of other turbofan engines and applied advanced noise reduction technology. This not only reduces the noise interference to the environment, but also makes the flight experience closer to the real sound of turboshaft engines. I believe that flight enthusiasts prefer to enjoy high performance while also experiencing a more realistic and immersive flight experience.
Application of 3D printing technology: Some key components of the T700 use the most advanced 3D printing technology. This technology provides us with extremely high design flexibility, can accurately produce complex component structures, and greatly shorten the production cycle. Through 3D printing, we can increase the complexity and precision of the design without sacrificing quality, ensuring that each product meets high standards of performance requirements.
Easy assembly:
2-3 hours to complete
Simplified assembly process: We have designed a simple and intuitive assembly process, and users can complete the assembly of the entire engine in 2 to 3 hours. Even users who are new to turboshaft engines can quickly master and easily complete the installation.
Easy to debug: Once assembled, users only need to make basic electrical connections and debug, and it can be put into use immediately, saving a lot of time.
Turboshaft Engine: How It Works
A turboshaft engine is designed to generate shaft power, primarily used in helicopters, power generation, and marine propulsion. Unlike turbofan engines, which produce thrust for airplanes, turboshaft engines deliver mechanical power to drive rotors or other machinery.
1. Power Generation
The engine produces shaft power by using turbines that absorb energy from hot, high-pressure gas. This gas is produced by the combustion chamber, which mixes atomized fuel with compressed air. The compressor section, powered by a gas producer turbine, compresses air and feeds it into the combustion chamber for combustion.
2. Compressor and Turbine
- The compressor is mounted on a hollow shaft and is driven by the gas producer turbine (which rotates independently of the power turbine).
- The power turbine, connected to the power shaft, converts the energy from hot gas into mechanical power, which drives the helicopter rotor.
3. Cooling and Efficiency
To protect the combustion chamber from extreme temperatures (up to 1700°C), much of the compressed air bypasses the combustion process and flows around the chamber, acting as a cooling shield. This helps prevent overheating and ensures efficient operation.
4. Reverse Flow Combustion
In a unique design feature, the combustion chamber in turboshaft engines has a reverse flow configuration. The airflow moves opposite to the main gas flow, optimizing combustion efficiency and reducing engine length.
5. Opposing Rotations
The power turbine and gas producer turbine rotate in opposite directions to reduce gyroscopic effects. This minimizes the angular momentum, making helicopter control smoother and easier.

Currently, our second-generation prototype is made of stainless steel. Although stainless steel has excellent strength and durability, there are also some challenges in the actual production process:
High cost: The processing and manufacturing cost of stainless steel is very high.
Easy to deform: When making complex components of turboshaft engines, stainless steel is prone to slight deformation during high-precision processing, affecting assembly and performance.
In order to solve these problems and ensure that every customer can get a cost-effective and stable quality product, we decided to optimize the final mass production version to an alloy material. Alloy not only maintains high strength and durability, but also has better processing stability, thus ensuring a more perfect appearance and performance of the model.
