SHERPA

CANSAT LAUNCHER

The second rocket project, following the successful launch of Stopař, allowed the Czech Rocket Society to take on the challenge of building a larger rocket. This rocket was designed, built, and launched for the national finals of the CanSat competition, providing the necessary authenticity for simulating a space mission.

The Sherpa project is the Society's latest rocket, developed in collaboration with ESERO, the educational office of the European Space Agency in the Czech Republic. Sherpa is designed for the CanSat competition, in which high school teams design mini-satellites that are launched to a height of 1km and then released, with the teams competing to collect the best possible data on the way back to Earth.

Sherpa is a 2.5-meter-long and 13 kg heavy rocket with a structure made of aluminum and PLA. It is designed to fly up to 1 km and release mini-satellites, with a total flight time of around 115 seconds. The rocket is powered by the same fuel as Stopař and can reach speeds of up to 180 m/s.

Given its more complex design, Sherpa underwent several formal demo flights and tests at Teplice airport. The official launch of Sherpa, comprising two rockets in total, took place on July 1st at Medlánky airport during the National CanSat competition finals, which the Society also helped to organize. The Society plans to be involved in future competitions and will continue to improve Sherpa in the future.
