Creating a Parachute Burrito Recovery System

This page describes the assembly of a parachute burrito system of dual deployment for HP rockets. This sort of system is useful in hybrid rockets where the longer motor casings make "zipperless design" difficult or impossible. The original burrito concept was developed by Marcus Leech; this is simply a detailed description of my implementation of the idea.

When I mention sizes or weights in this page, remember it is for this rocket only. You must engineer the various components to meet the stresses they will encounter. This can only be determined after major assembly is done and weights can be verified. This rocket (Noxious Nellie) is 4" x 72", and weighs in at 6.5 lbs. It is designed to fly on 38mm hybrid casings. Though I guess you could use APCP.

The recovery system is composed of several parts, labeled in the photo above. Click a link below for more information on that component.

• Electronics bay

• Recovery harness

• Burrito Blanket

• Main Chute  (includes packing instruction)

• Sabot

• Drogue Chute

• Shock Absorption

The system must be packed into the rocket in a specific packing order.

Materials

The material for the sabot and burrito blankets is Aramid cloth, obtained from Pratt Hobbies.

The Euroblock connectors can be obtained from Aerocon Systems.

Both Pratt Hobbies and Aerocon sell the plastic 2ml charge containers I use.
