This EDF has been tested with 25KW JLM-11070/28S motors, offering a reliable and performing configuration. Numerous tests were conducted during construction and simulation to achieve our goal of providing the highest levels of efficiency and quality.
The efficiency refers to the low electrical absorption converted into high static thrust and high speed of the jet, all this is possible thanks to the optimal static and dynamic balance and the rotation torque.
With this new Electric Ducted Fans of very particular dimensions, we intend to reach the customer who no longer uses it only at the RC level but above all on VTOL aircraft and other special applications.
The design of this new EDF system is based on the technological know-how accumulated thanks to the creation of numerous prototypes carefully tested in recent years. All EDF components are designed as accurately as possible by a company specializing in the CNC sector; 7075 aerospace aluminum is used for the construction of the metal parts in question, in this way it is possible to obtain maximum efficiency both in terms of mechanical strength and weight.
The fan is not composed of individually glued blades but is conceived in a unibody frame in carbon fiber that is completed with the turned 7075 aluminum components. The choice of creating 10 blades proved to be the best compromise between static and dynamic thrust.
The rotation speed was deliberately kept low with a value of around 18,000 rpm. Along with the fan, an air cooling system was also designed for the engine.
The motors are interchangeable according to the customer's needs.
Operation of the engine outside the specifications listed above can damage it or the battery and regulator. It is important that the motor and controller are set correct operating the engine outside of the specifications listed above may cause damage to the engine or the battery and regulator.
It is important that the engine and regulator are set correctly in the following cases otherwise the warranty can be voided. We strongly recommend using a watt meter to test performance when setting up a new system. If the current output is higher than the factory recommended specifications, then it must be adjusted by the controller (esc).
The TIMING and THROTTLE CURVE settings on the controller can help you set the appropriate levels.
At VasyFan, we offer comprehensive flight training programs for pilots of all levels. Our experienced instructors will guide you through every stage of your training, from your first solo flight to your advanced certifications.
