Have you ever dreamed of creating a mechanical bird that soars through the air with the elegance of nature? Well, in this captivating journey, the creator of an ornithopter takes you behind the scenes of building a rocket bird from scratch.
Starting from ground zero, the creator faced the daunting challenge of constructing a vertical-flying aircraft without relying on electricity. The adventure kicked off with the design and testing of various wing variations, leading to the creation of what might be the lightest air motor in existence. This motor, featuring a unique rotary vein design, blends elements of a turbine and a piston engine, promising a revolutionary flight experience.
Encountering hurdles in the form of viable gas cartridges, the creator ingeniously harnessed the power of carbon dioxide to drive the wing mechanism. A lever linkage system converted rotational energy into an oscillating motion, amplifying the range of each graceful wingbeat.
Exploring options for converting gas energy, the creator experimented with a hybrid approach, resulting in a rotary vein motor that underwent meticulous 3D printing. Overcoming challenges with inlet holes and air direction, the motor eventually roared to life, spinning at an impressive 14,000 RPM at 130 PSI.
The journey didn't stop there. Gearing became a crucial addition, with small plastic RC gears and a careful selection process leading to an optimal 1 to 8 gear ratio. Thrust testing revealed the exhaust accounting for a significant 43% of the system's thrust, prompting a complete redesign with 3D printing to save weight and enhance performance.
As the rocket bird took shape, challenges persisted. CO2 cartridge cooling issues arose, leaving the rotor frozen and coated in black residue. The creator contemplated solutions, demonstrating resilience in the face of setbacks.
In the final leg of this adventure, the creator discussed the limitations of CO2 cartridges, proposing a metal push-fit connector and the air hose's weight as new ballast. A glimpse into Wing 4 and nozzle one showcased an impressive total thrust, though stability issues demanded attention.
Amidst the technical intricacies, the creator emphasized the role of CAD tools like OnShape, enabling collaborative design work accessible across devices.
