HBM enhances safety on space shuttle
HBM's
data acquisition and analysis equipment is being used to monitor the loads
affecting NASA's space shuttle Discovery during its preparation and launch
sequence. HBM's equipment is a key part of the shuttle's critical data
acquisition system for monitoring the loads during ground operations.
The equipment is fitted to the Mobile Launch Platform (MLP) and connected
to each of the 8 tie-down points which secure the space shuttle in place.
NASA needs to monitor the loads to ensure that the weight is equally distributed
across the tie-down points. The data acquisition system is networked with
the NASA Launch Control Center, allowing mission controllers to take appropriate
corrective action easily.
Monitoring is required throughout the assembly of the space shuttle through to its roll out to the launch pad and final launch at the Kennedy Space Center in Florida. The operation is critical to the space shuttle's safety as the loads at the tie-down points vary, especially while inserting the payload and filling the tanks with liquid propellant. The loads must be kept within acceptable limits while the space shuttle remains on the ground to avoid adversely affecting the structural integrity of the launch vehicle and its operational performance. All of the equipment is capable of withstanding the high temperatures, shock and vibration associated with the launch sequence. Because the equipment is a critical system it has to meet stringent criteria imposed by NASA to ensure it provides accurate information throughout the shuttle launch process.
The next shuttle launch, designated Discovery's Return to Flight Mission, is planned for May/June this year and will include delivery of the logistics module to the International Space Station.
