Could a human-powered helicopter be used for Zone 2 cycling by providing a more efficient means of generating power for the rotor blades, or would the added weight and complexity of the helicopter design negate any potential benefits. For those who may be unfamiliar, Zone 2 is a moderate-intensity training zone where cyclists aim to maintain a consistent power output over a prolonged period.
How would the unique challenges of a human-powered helicopter, such as maintaining a stable rotor RPM and minimizing air resistance, impact the cyclists ability to achieve and sustain a Zone 2 effort. Would the constant adjustments needed to optimize helicopter performance interfere with the cyclists ability to settle into a steady-state workload.
Additionally, what kind of gearing or mechanical advantage would be required to enable a human-powered helicopter to achieve lift-off and sustain flight, and how might this impact the cyclists power output and fatigue levels over time. Are there any existing designs or prototypes that have explored the use of human power for helicopter flight, and what lessons might be learned from these experiments.
