This report is on the development of a pop-pod system which addresses two significant problems for those who fly Boost Gliders.
One problem was the pop-pod getting hung up on the glider after ejection, commonly called a Red Baron. Through a series of design improvements and testing, a pop-pod system called "Spooler" was developed. The Spooler ejects off the nose section, which tumbles down safely, exposing a wrapped up (spooled) streamer in the main pod so it can unspool and bring the main pod down safely
The other problem was how the glider attaches to the pod. Common hook attachment methods are sometimes too loose so the glider comes off early, too tight so the glider does not come off of the pod at all, or inconsistent fit between different pods and gliders of the same design. This problem was
first attacked by the use of a "universal" cast glider hook design, later sold commercially by Apogee Components. However, that design had some drawbacks in allowing gliders to come off a bit too easily, and were somewhat large. So, a dual interlocking hook system was developed, which
did not allow the glider to come off until the pod slid backwards a certain distance (usually 1/4") at ejection. Called the "L Hook" due to the hooks being similar to very short but wide "L's", they also have a lower profile than the Apogee Universal hooks. Being cast parts, they have a consistency of fit
that allows any glider to be attached to and flown by any pod that uses the same hook size.
When combined, a Spooler Pod and cast L hooks make for a very reliable pop-pod system for Boost Gliders.
