About Wendernes

Wendernes is a Swedish research and development organization dedicated to advancing hypergolic propulsion technology.

What We Do

We design and test smaller rocket engines using hypergolic propellant systems. Our primary work centers on hydrogen peroxide (HTP) monopropellant systems and white fuming nitric acid (WFNA) bipropellant systems.

Our Expertise

Propellant Chemistry: Development of IWFNA (inhibited white fuming nitric acid) with iodine pentoxide as corrosion inhibitor
Engine Design: Smaller liquid-fueled rocket engines for suborbital applications
Systems Testing: Ground testing and performance characterization of propulsion systems

Focus

Suborbital research applications—atmospheric testing, trajectory analysis, and propulsion system validation. We are not pursuing orbital launch capability.
