LAPLander - a student rocket project
"Light Airbag Protected Lander"
Critical Design Review
2009-02-23 - 2009-02-28
Preliminary Design Review, Germany
LAPLander accepted to fly on the REXUS 7/8 Rocket!
(launch March 2010)
The team presented the LAPLander project and design for the ESA jury. Tales and images can be found here!
The detailed LAPLander presentation can be found here
The first fall and impact tests have been made, have a look at the videos..
"impact test" &
Images of the LAPLander prototype are now available online
The objective of the project is to design, build and validate a
prototype of a small ejectable sounding rocket payload capable of
collecting data in an on-board memory. The LAPLander design
concerns the airbraking, impact protection and recovery systems,
along with the study of flight characteristics to evaluate the payload
The project has been submitted as a proposal for flight on ESA's REXUS 7/8 rocket campaign for student experiments,
which have a scheduled launch March 2010.
See our public presentation for more info.
The main components of the payload include the following:
- An airbraking and impact protection system (light green), based on
inflatable airbags that serve both to decelerate the payload and to
protect it at the moment of impact.
- Control unit and sensors (dark green)
- 4 Dummy SCALE electric field wire boom units (gray)
- A redundant recovery system using both a radio beacon and a satellite commmunication module (Not shown on CAD)
The detailed LAPLander proposal for REXUS 7/8 can be found HERE
The LAPLander team consists of students from KTH (left to right):

The team is lead by Torbjörn Sundberg, PhD student at the department of Space and Plasma Physics, and
supervised by Dr. Nickolay Ivchenko.

The REXUS program is a sounding rocket program for university students and aims to provide practical experience from a real space project. REXUS is a
implemented by the Swedish Space Corporation (SSC) together with Deutches Zentrum für Luft- und Raumfahrt (DLR) and the European Space Agency (ESA), and financed by the Swedish National Space Board and DLR. The basic idea behind REXUS is to provide an experimental space platform for students.
