SolarStratos: To the edge of space

SolarStratos Partnership

Accelerating the future of solar aviation with SolarStratos

At Fischer Connectors, we believe anything is possible.

SolarStratosAs an official partner of SolarStratos, an ambitious project to send the first manned solar plane to the stratosphere, we are testing the boundaries of possibility. By combining high-performance connectivity with ingenuity and innovation, we’re helping push the limits of solar aviation to the edge of space.

The Partnership

SolarStratos aims to revolutionize solar-powered transport and accelerate the future of aviation— which means facing daunting technical challenges in an extreme environment.

As an official partner, Fischer Connectors is helping address those challenges. Drawing upon more than 60 years of expertise in connectors and cable assemblies, we work with the SolarStratos team to:

  • Develop customized connectivity solutions with an optimum weight/ performance ratio
  • Transmit large volumes of data from the plane to earth
  • Ensure reliability and safety in extreme environments

The Project

Raphaël DomjanSolarStratos’ mission is to demonstrate the potential of renewable energy— exploring new frontiers of solar-powered and electric aerial vehicles, and opening the door to commercialization.

The SolarStratos plane is propelled solely by solar energy, backed by a Li-ion battery. It will be the first piloted solar-powered aircraft to enter the stratosphere, and the first solar-powered twin-seater commercial aircraft in history.

The project is led by SolarStratos’ founder and pilot Raphaël Domjan, and is supported by an international team of engineers, a former astronaut, pilots, meteorologists and doctors. On the five-hour mission, Domjan will wear an astronaut’s pressurized suit powered uniquely with solar energy—a global first.

The Impact

Our partnership combines technology, innovation and experience to push the limits of what is considered possible in solar-powered aviation. Together, we’re creating energy-efficient solutions that will revolutionize transport while protecting the environment for future generations.
