Sluggish Flight of the Aircraft Due to Powerful Wing Gusts
The world of RC aviation has seen a new addition with [rctestflight]'s latest project - a blown wing RC airplane designed for Short Takeoff and Landing (STOL) operations. This unique model, made from foam and pink styrofoam, showcases an impressive short takeoff distance, particularly for a seaplane.
At the heart of this design is the use of electric ducted fans (EDFs) mounted along the wing chord. These fans push air through a plenum inside the airframe, expelling it out a slot on the top surface of the wing. This setup creates a high-pressure zone that delays stall and sustains lift even at slow flight speeds, making it ideal for STOL operations.
The blown airflow allows the model to take off and land in a very short distance by flying close to stall speed but still maintaining controllability. The EDFs serve both as propulsion and as a critical part of the control mechanism. To ensure safety and durability, the aircraft includes components such as an Ardupilot autopilot system, radio receiver, and battery with crash-resistant construction.
[rctestflight] has been publishing videos demonstrating this 100% blown wing powered RC airplane on YouTube and Instagram, showcasing its unique design and STOL capabilities. In these videos, you can see the aircraft in action, with detailed tests and flights providing a comprehensive look at its performance.
However, while this concept is innovative in RC aviation, it would be deemed too risky for manned aircraft. The critical reliance on continuous engine thrust to maintain lift means that engine failure at low speed could cause the plane to stall without sufficient glide capability.
[rctestflight], known for their history of building various innovative projects, including human-carrying hydrofoils, solar soarers, and a 3D-printed rover-tank, continues to push the boundaries of what's possible in the world of RC aviation. Their blown wing RC plane is a testament to their ingenuity and their commitment to advancing the field.
In summary, [rctestflight]’s blown wing RC plane is a novel, foamboard-based model that uses EDFs blowing air over wing slots to enable very slow flight and short takeoff and landing. This innovative design, while not suitable for manned flight due to safety concerns, demonstrates the exciting possibilities that lie ahead in the world of RC aviation.
