High-Speed Drogues

Extract and stabilize heavy payloads at extreme Mach numbers with robust drogue architectures.

How we approach High-Speed Drogues

Traditional textiles fail catastrophically at supersonic speeds due to immense dynamic pressure and kinetic heating. We engineer high-speed drogue parachutes utilizing advanced aramid fibers and specialized ribbons to survive deployment in trans-sonic and supersonic flight envelopes.

The primary function of the drogue is to stabilize tumbling payloads - such as ejecting capsules or descending ordnance - while rapidly bleeding off airspeed to a velocity where main parachutes can safely deploy.

We utilize extensive computational fluid dynamics (CFD) to model the wake turbulence of the parent craft, ensuring the drogue inflates cleanly behind the payload rather than becoming entangled in the low-pressure slipstream.

Wind tunnel testing is critical. We simulate the blistering deployment sequences in specialized aerospace wind tunnels to validate structural margins before risking hardware in the sky.

Surviving the Shockwave

Extracting a parachute at Mach 1.5 requires materials and geometry fundamentally different from standard skydiving equipment.

High-thermal-resistance materials.
Wake-turbulence inflation modeling.
Precise staging integration.

The Porosity Crux

A solid canopy deployed at supersonic speeds creates a bow shock that prevents proper inflation or tears the fabric. Drogues use high geometric porosity, deliberately letting air pass through to maintain stable, rigid hemispherical shapes.
