## Parachute Recovery Systems Design Manual

Really cool document that has basically all the fundamentals of most parachute recovery systems. A great reference for even small-scale parachute development.

## Simple Guide to DIY Disk Gap Band Parachutes

Disk Gap Band parachutes are a really cool balance between stability and drag. The topic regarding Disk Gap Band Parachutes can get extremely technical, but Apogee has released a very good balanced guide for beginners. It even has tutorials on how to make your own! We found this article to be very helpful when we were starting out with our parachute dev.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.k9rockettech.com/research-resources/parachute-design.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
