The current slidewire basket system used for Shuttle crew and pad workers will be removed, with a new system installed into the taller pad configuration for the Ares program. <\/font><\/font><\/p>\n NASA is required to design the system \u2018for a safe mode of emergency egress from the crew hatch of the CEV (Crew Exploration Vehicle\/Orion) to a safe area for flight crew, closeout crew, contingency crew, and ground operations personnel while the CLV is at LC-39B.\u2019<\/p>\n During the trade study, detailed analysis was performed on the following system elements: Ingress\/egress routes for Pad flight and Ground Support Equipment (GSE) configurations. Operational tasks with associated manloading. Operations hazard levels and flight\/closeout\/contingency ground crew personnel emergency egress route criteria.<\/font><\/p>\n Previous studies for Shuttle and Apollo were used as guidelines, such as the Shuttle\u2019s slidewire baskets to a bunker away from the pad, and Apollo\u2019s high speed elevators to a blast room.<\/p>\n In total, four major concepts were put forward as Ares EES candidates: 1) Four to six separate four-man cab slide-wire systems to the safety bunker from the Fixed Service Structure (FSS) or Mobile Launcher (ML) tower. 2) Four separate four-to-six man car rail (rollercoaster) systems to the safety bunker from FSS or ML tower. 3) Elevator system to Pad Terminal Connection Room (PTCR) to blast room from FSS or ML tower. 4) Slide-tube system to safety bunker from FSS or ML tower. <\/font><\/p>\n The study defined the options as follows: <\/p>\n <\/font> \u2018This system will be start from the crew access arm level of the ML tower or FSS and terminate at a bunker located on the west side of the pad just outside of the perimeter fence.\u2019<\/p>\n Rail Car (Rollercoaster) System:<\/u><\/em><\/font><\/font><\/p>\n Spaceflight history books (adsbygoogle = window.adsbygoogle || []).push({});<\/p>\n \u2018The rail would follow the ML tower vertically down to the pad surface, then turn and continue close to the ground to the safety bunker. A passive magnetic and friction braking system will decelerate the cars at the track\u00e2\u20ac\u2122s end as well as prevent the cars from hitting each other.\u2019<\/p>\n <\/font>High Speed Elevator Alternative:<\/em><\/u><\/p>\n \u2018The egress route would be across the access arm, down the high-speed elevators, into the slide tube, and then into the existing blast room beneath the pad.\u2019<\/p>\n Slidetude System:<\/u><\/em><\/p>\n \u2018A fixed slide tube made of either metal or hard plastic\/fiberglass will extend from the access arm level of the ML tower or FSS to the existing bunker located on the west side of the pad.<\/p>\n The study listed its recommendations for the best EES option as the Rollercoaster\/Rail Car system, despite it being the most expensive system \u2013 ranking it both first and second (from the RSS and the ML Tower), beating out the Slidewire, Elevators and Slidetube systems.<\/p>\n Further fine tuning and modifications to the designs are expected, with the Rollercoaster cars likely to be semi \u2013 or fully \u2013 enclosed, to protect escaping crew and\/or workers from being sent into the path of an event, such as a hypergolic leak \u2013 which would be a serious issue if they weren\u2019t enclosed in the cars.<\/p>\n Also relevant to the final design will be the call for a \u2018clean pad\u2019 \u2013 which would have impacts on such EES concepts.<\/p>\n The schedule calls for the fabrication of the design to start at the start of 2008, ready for installation into the pad in 2009.<\/font><\/font><\/p>\n Other L2 Resources For Ares I, V and Constellation: Ares I-1 Test Flight Plan (full outline) Presentation.

Currently, Shuttle launch pad complex 39B at the Kennedy Space Center (KSC) in Florida will be handed over to Constellation on April 1, 2007. The pad will undergo stages of major modification, firstly for the test flight of Ares I-1 \u2013 and subsequent test flights, and again for the first manned launch using Ares I.<\/p>\nSlide-wire System:
<\/u><\/em>
\u2018A slide-wire system will be used from the crew access arm level of the ML tower or FSS to a bunker located on the west side of the pad. One basket will be attached to each slide wire and have a four person capacity. <\/font><\/font><\/font><\/p>\n\u2018An unpowered fixed single-rail system from the access arm level of the ML tower to the existing bunker would be used. The railcars could be enclosed to provide personnel protection. Each railcar can hold four to six people.<\/font><\/p>\n
\u2018The egress route will be across the access arm to the slide tube, down the slide tube to the bunker, and into the bunker. Each person would enter the tube one at a time from the crew access level on the tower and slide the distance to the bunker.\u2019<\/p>\n
