AI Technical Summary

Technical Problem

Traditional ground transportation methods have long construction cycles and high costs. eVTOL faces significant challenges in terms of wind resistance, stability under complex weather conditions, battery technology bottlenecks, difficulty in obtaining airworthiness certification, air traffic management pressure, and public safety and policy risks.

Method used

An I-shaped track constraint system for aircraft is provided, comprising an aircraft, a control surface adjustment device for altitude and orientation constraints, and an I-shaped track. The aircraft is kept within a preset range by adjusting the altitude and orientation constraints. The design of the I-shaped track reduces the turning radius and climbing angle, thereby reducing construction and maintenance costs.

Benefits of technology

It reduces the risk of aircraft collisions, avoids airspace approval pressure, improves safety and operational efficiency, reduces construction and maintenance costs, is suitable for efficient transportation between small and medium-sized towns and large transportation hubs, reduces the requirements for foundation settlement, and reduces reliance on sensors and batteries.

Abstract

The invention discloses an aircraft restraining system restrained by an I-shaped track and a flight restraining method used for limiting the track. The I-shaped track comprises a track top plate, a track bottom plate and a middle vertical plate. Each set of control surface adjusting device comprises a height constraint adjusting mechanism and a direction constraint adjusting mechanism; horizontal control surfaces on two sides of the aircraft at the same spanwise position are correspondingly connected with a set of height constraint adjusting mechanism, and a vertical control surface is connected with one or two sets of direction constraint adjusting mechanisms; the height and direction restraining and adjusting mechanism and a track structure on one side of the I-shaped track form a floating connecting structure; in the process that the aircraft flies along the I-shaped track, the horizontal control surface is driven by the height constraint adjusting mechanism to deflect, and the vertical control surface is driven by the direction constraint adjusting mechanism to deflect, so that reverse acting force is generated, and the relative distance between the aircraft and the I-shaped track is kept within a preset range. The problems existing in a traditional ground traffic transportation form and an eVTOL transportation form are solved.
