MX Transporter Emplacer Guidance and Control,
BOEING AEROSPACE CO SEATTLE WA
Pagination or Media Count:
The MX Transporter Emplacer TE is the largest rubber tired vehicle in the world. It is 165.5 ft long, 29.8 ft high, 21.8 ft wide and weighs 1,450,000 lbs. The TE was developed to provide test data for use in the design of a fleet of large vehicles that will be required to transport MX missiles between protective shelters. It was developed specifically for the vertical shelter MX basing mode, but has provided valuable information on the performance of large rubber tired vehicles applicable to other basing modes. The TE required precise positioning to allow emplacement and removal of the capsule and testing has demonstrated that the automatic near shelter positioning system developed for the TE meets this accuracy requirement. The automatic control system developed for the TE in over-the-road mode allows road width to be determined almost entirely by driver performance, with relatively little additional road width required to provide for off tracking of the front and rear tractors. TE test results demonstrate that a large rubber tired vehicle similar to the vehicles that will be deployed as part of the MX program can be positioned precisely at a shelter and can be steered with sufficient accuracy to minimize road costs.
