Development programme

Flight test vehicles

Rockets built to isolate risk, validate new systems in flight and carry proven technology into larger competition vehicles.

Active roll-control demonstrator

Sguaba
Tuinne

Sguaba Tuinne is HiPR's flight-test vehicle for active roll control. Canards mounted in the nose alter the vehicle's roll in flight, creating a practical route from wind-tunnel data to closed-loop control on a rocket.

The first campaign was cut short by a motor failure. Rebuilt and reflown, the vehicle subsequently demonstrated the experimental canard system in flight and supplied the data needed to scale the architecture toward supersonic vehicles.

Pneumatic recovery demonstrator

Feth
Fiada

Feth Fiada was built to move HiPR's CO₂ recovery concept out of the workshop and into repeated flight. The 3-inch vehicle used a servo-driven, flame-hardened steel piston to pierce a 16-gram CO₂ cartridge and pressurise the recovery bay.

Three flights exposed the system to real launch loads and recovery conditions. Each test informed the larger twin-cartridge assembly later integrated into Badhbh.

First high-powered vehicle

Sionna

Sionna was HiPR's first high-powered rocket: a 3-inch vehicle built to establish the team's manufacturing, launch and flight operations before the first international competition campaign.

It flew stably on a J motor to approximately 1.5 kilometres during International Rocketry Week in Glasgow. The recovery failure provided the operational lessons carried into EuRoC 2024.
