The need for long runways in aviation creates significant limitations, from high land costs to restricted operations in urban or remote areas. While solutions like catapult systems exist, they are often impractical for commercial use. One way to address this could be a ground-based system that creates relative motion between the aircraft and the air, allowing shorter takeoff distances by simulating forward movement without requiring the plane to physically accelerate over a long runway.

How the System Could Work

The concept involves a high-powered, ground-based mechanism—similar to a treadmill or conveyor belt—that moves beneath a stationary aircraft. This would enable the wings to generate lift without the plane needing a long runway. Key features might include:

• Scalability: Starting with smaller aircraft (drones, private jets) before expanding to commercial planes.
• Modularity: Integration into existing runways or standalone deployment for temporary use.
• Energy recovery: Potential to recapture kinetic energy during deceleration for future landing applications.

Potential Applications and Stakeholders

This system could benefit multiple groups:

• Urban airports: Expanding operations without acquiring more land.
• Military and naval operations: Enabling shorter takeoffs on aircraft carriers or remote bases.
• Private aviation: Allowing larger planes to operate from smaller airfields.
• Drone logistics: Facilitating rooftop takeoffs and landings for urban delivery hubs.

Stakeholders like airports and militaries might see strategic advantages, though upfront costs and regulatory hurdles could pose challenges.

Execution and Comparisons

An MVP could begin with a small-scale prototype for drones to validate the physics. Compared to existing solutions like catapults or JATO rockets, this system could offer reusability, lower operational costs, and broader applicability without requiring aircraft modifications. Early adoption might focus on high-value niches like military or private aviation before expanding to commercial use.

While the idea is scientifically plausible, engineering and regulatory challenges remain. Starting small and focusing on takeoff before tackling landing could help mitigate risks.
