Launch Equipment & Pad

The launch pad, which consists of the service tower, to which a launch rail is mounted, is an
assembly to rmly book the rocket before launch, so that the launch itself can be prepared
and a desired horizontal and vertical alignment can be adjusted to achieve a speci fic hight
path. Furthermore the service tower provides an interface to conduct service operations on
the rocket. For instance measurement hardware and feed and supply lines are integrated,
partially to manoeuvrable elements which can be released straight before launch. With the
launch pad as interface, various system parameters and ambient conditions can be acquired
and monitored from inside the TSZ. The other way round the signal for ignition can be given
or the launch can be aborted at any time in a case of emergency. The disconnection of all
service lines is a critical process and must work absolutely reliable and free of compromise to
assure a succesful launch of the rocket.
The tower will consist mainly of premanufactured of -the-shelf traverses (ITEM), to wich all service
devices and a launch rail are mounted. The tower has a height of ca 10 m. This guidance length
is needed to accelerate the rocket for a sucient aerodynamic stabilisation. The whole launch pad
will be set up in the desired direction for a de ned horizontal alignment. The elevation can be adjusted
from 0 to 90 via a according pivot at the baseplate. Therefore not only the tower itself can be
assembledeasily on ground, but also the rocket can be integrated and inserted horizontally in the
launch rail.
This principle is analogue to the 11,3 m long MRL launcher at Esrange.
The biggest di fference between the MRL launcher and the envisaged design is that the MRL is stationary. The SRP launcher has to achieve the same stability without loosing its ability to be transported easily. To ensure this, the baseplate with the centre pivot has four pedestals. These extension simultaneously serve as attachments for the tension belts, which are used for raising and crabbing of the tower. It is possible to additionally pin the extension pedestals down to the ground. After integrating the rocket, the tower can be raised via one or more hand ratchets at the tension belts. Also the desired elevation is adjusted with the hand ratchet, yet can be locked into position by a pole in a slide mounting.
