Cornering and wear behavior of the Space Shuttle Orbiter main gear tire
TLDR
In this paper, the impact of load and yaw angle on the cornering behavior of the main gear tire of the Space Shuttle Orbiter main gear tires was investigated at the NASA Langley Research Center Aircraft Landing Dynamics Facility.Abstract:
One of the factors needed to describe the handling characteristics of the Space Shuttle Orbiter during the landing rollout is the response of the vehicle's tires to variations in load and yaw angle An experimental investigation of the cornering characteristics of the Orbiter main gear tires was conducted at the NASA Langley Research Center Aircraft Landing Dynamics Facility This investigation compliments earlier work done to define the Orbiter nose tire cornering characteristics In the investigation, the effects of load and yaw angle were evaluated by measuring parameters such as side load and drag load, and obtaining measurements of aligning torque Because the tire must operate on an extremely rough runway at the Shuttle Landing Facility at Kennedy Space Center (KSC), tests were also conducted to describe the wear behavior of the tire under various conditions on a simulated KSC runway surface Mathematical models for both the cornering and the wear behavior are discussedread more

TL;DR: In this article, an experimental investigation was conducted to evaluate cornering characteristics of the 32 x 8.8 nose gear tire of the space shuttle orbiter, which was tested on a dry concrete runway at nominal ground speeds ranging from 50 to 100 knots and over a range of tire vertical loads and yaw angles.
A study of the cornering forces generated by aircraft tires on a tilted, free-swiveling nose gear
R. H. Daugherty,S. M. Stubbs +1 more
TL;DR: In this paper, the effect of various parameters on the cornering forces produced by a rolling aircraft tire installed on a tilted, free-swiveling nose gear was evaluated by measuring the impact of these parameters on a modified vehicle as it was towed slowly.
