Dynamics and Energy Conversion of Aircraft Landing Gears at Touchdown

Automated Aircraft Touchdown

In this paper, we explore the challenging and important problem of automated aircraft landing. We created a simulator to be able to perform online experiments in various conditions including stormy weather and starting from off-trajectory starting points. We experiment with a wide range of techniques to learn the optimal flight policy including reinforcement learning, Monte Carlo based dynamic ...

Numerical Simulation of Landing Aircraft Dynamics

Preliminary note Numerical simulation procedures for landing dynamics of large transport aircraft are briefly presented. Developed numerical procedures allow for determination of dynamic response of landing aircraft for different flight and touch-down parameters. A non-linear dynamic model of landing aircraft, which serves as a basis for computational procedures, is synthesised by modelling of ...

Aircraft tire temperature at touchdown with wheel prerotation

Aircraft landing problems with aircraft classes

This paper focuses on the aircraft landing problem that is to assign landing times to aircraft approaching the airport under consideration. Each aircraft’s landing time must be in a time interval encompassing a target landing time. If the actual landing time deviates from the target landing time additional costs occur which depend on the amount of earliness and lateness, respectively. The objec...

Visual perception of touchdown point during simulated landing.

Experiments examined the accuracy of visual touchdown point perception during oblique descents (1.5 degrees -15 degrees ) toward a ground plane consisting of (a) randomly positioned dots, (b) a runway outline, or (c) a grid. Participants judged whether the perceived touchdown point was above or below a probe that appeared at a random position following each display. Although judgments were unac...
