Randwulf's Ellipsoidal Parachute for Model Rockets

Randwulf's Ellipsoidal Parachute for Model Rockets A nose cone descends on a blue and yellow parachute.

by Randall Whitlock

A computer-designed sewing pattern

This pattern describes a basic dome-shaped parachute suitable for use in model and high-power rockets.

The pattern is ellipsoidal in shape (the top half of an oblate spheroid for you math wizzes). This shape is created by sewing together eight or ten gores, which are formed like triangles with the sides bowed outward. A "spill hole" in the center strengthens the chute and improves stability of descent.

Moira swings the parachute in the air.

The pattern package includes:

An 11 by 17-inch pattern sheet for eight-section parachutes with 12 to 24-inch diameters

A 24 by 36-inch pattern sheet for ten-section parachutes with 24 to 48-inch diameters

An illustrated instruction manual.
