Rocketarium Frangible ARCAS Rocket During the 1960's, the Frangible ARCAS was developed as a rocket that could be flown over residential areas. To avoid damage to property, or injury, upon landing, the rocket was destroyed in mid-air. It has a sheet of explosive material wrapped around the airframe. Once the explosive was triggered, the rocket was reduced to particle sizes with acceptable levels of kinetic impact energy. The scale Frangible ARCAS model separates at motor ejection and descends under a parachute. The kit doesn't get blown to pieces and can enjoy many flights, as opposed to the real deal. Dimensions Total length : just over 3 foot (36.5") Diameter : 1.637" (BT60) Fin Span : 4.647" Weight : 4.4oz Manufacturer Recommended Rocket Engines Estes D12-5 Single Use Aerotech E20-7 Reloadable Aerotech E18-7, E28-7, F24-7 Challenges: The explosive sheet wrapped around the airframe is created by cutting two short tube sections and gluing them onto the airframe.
