Case Study: The Endless Runway

Endless Runway is a essential and original airport idea, which applies a circular runway. The idea of the Endless Runway can create a discovery in sustainable airport capacity by avoiding the physical constraints of conventional runways through shifting the lift-off and touchdown of different aircraft. The main feature of the circular runway is that it will develop possible to let an aircraft operate always at landing and take-off with headwind. Whatever its strength and direction, the Endless Runway becomes liberated of the wind. When permitting limited crosswind, airspace users can shorten the global trajectory of the flights through improved departure and arrival directions

The circle of the runway will requirement to be large enough to

In both cases, the geometrical properties of the runway are same.

• The runway internal radius is set to 1500 meters. Thus the whole runway length, of about 10 000 meters, is long enough to operate some aircraft simultaneously on the runway and to build airport structures inside, while keeping the airport compact.

• The runway width that can be used by aircraft is set to 140 meters as a compromise between discomfort due to higher centripetal acceleration for a thinner runway and the cost of a wider runway.

• The runway width that can be used by aircraft is set to 140 meters as a compromise between discomfort due to higher centripetal acceleration for a narrower runway and the cost of a wider runway.

• In order to limit the effects of the centripetal force, the circular runway lateral profile is banked with increasing angles from (Figure

One multi-story car park can be situated under the hump of the airstrip (Fig. 6) to improve the use of the runway volume. In connection with the 18 runway parts, arrival and departure routes have been defined. Departure routes start at the end of the respective runway part climbing straight out to a height of 5000 feet with an angle of 5°. Entrance routes end at the beginning of a runway segment with a straight path coming from a height of 3000 feet and a slide path angle of 3°. The opening point of the arrival routes and the end point of the departure routes are indicated by TMA (Terminal Manoeuvring Area) entry and exit points. shows a plan view of the TMA routes network with the circular runway in the mid, and shows their vertical
