        沒有載人的東西要控制離不開電子系統，另一種開傘方式就是電控開傘了。


        因為是電控，判定開傘需要的條件可以有彈性的多，可以依據自己的需求裝適合的感測器和控制板，例如用陀螺儀測量加速度推算火箭目前的飛行階段、測量傾角推算火箭目前的飛行姿態、裝氣壓高度計、計時器，甚至搞個

        談談探空火箭回收的那檔子事。為什麼要回收火箭?
一來要回收無價的數據，當然可以用無線傳輸之類的方式及時回傳給地面，但多一份總是比較好(更何況是沒裝無線傳輸功能的那種)。
二來是避免值錢的東西摔個粉碎。
三來是避免組裝或製作很麻煩的東西摔個粉碎。
四來是總之得避免火箭(或是火箭殘骸)砸

From duct tape rockets, to sugar motors with time delays and parachute ejections charges.

This is a follow up to my previous video on how to make Sugar Rockets (http://bit.ly/SugarRocket)

WARNING: 

Rockets are not toys, and this project really should not be duplicated.  This video is mainly for educational and demonstrational purposes.  If you’re going to attempt it anyway, I highly suggest contacting local rocket clubs to become familiar with local laws, and how to stay out of trouble with the FAA, and avoid hurting any people or property.  Playing with unstable rocket motors could result in serious injury, property damage and/or legal ramifications.  Use of this video content is at your own risk.

You should be aware that misuse, or careless use, of rocket propellants or ignition of an incendiary or explosive material may not be legal in your area.  Check local laws and inquire with local rocketry clubs on how to safely make and launch sugar rockets.

Project Inspired By:  

A few comments from viewers suggesting to combine two previous projects to see what would happen.  The delay mix and ejection charges came from the book “Easy PVC Rockets” by Jason Smiley. (http://bit.ly/IBEasyPVCRockets) If you check out the link, please share the love and let Jason know that Grant Thompson sent you. :)  Thank you!

My friend NightHawkInLight also has an awesome video on a different method of making a cored rocket with black powder.  You can see that here: http://bit.ly/IBBPCoredRockets

Project History & More Info: 

In a previous video on how to make sugar rockets (http://bit.ly/SugarRocket) I promised to show how to make a delay mix and a parachute ejection charge.  

I would caution anyone wanting to launch a duct tape rocket without a parachute to take every precaution imaginable.  These are not toys.  They can light things on fire, and fall down on peoples heads, which I imagine could cause serious injury.  You may need permits, or only be able to launch these on special experimental launch days with local rocketry clubs.

My launch was out in the middle of the dessert, miles and miles away from any people, property and anything flammable.  Safety precautions were in place in case anything went wrong.

I wanted to demonstrate what happens to a rocket without a parachute.  You can see it basically becomes a lawn dart.  And while rockets should never be launched in an area close to people, property, or highly flammable materials to begin with, they really need to have a parachute to retard the descent rate to minimize potential damage.

I made another rocket with PVC, and a parachute from a big black garbage bag and static tested the ejection charge multiple times, with 100% success.

I didn’t have a chance to launch the rocket to test the charge while air born, but I’m extremely confident there is plenty of power to push a parachute at apogee.

I’m thinking about making a project video showing how to make a rocket with a parachute from scratch, so if you’d like to see me do something like that, leave a comment letting me know.

Once again I want to reinforce that playing with rocket motors could result in serious injury, property damage and/or legal ramifications.  I highly suggest contacting local rocket clubs to become familiar with local laws, and how to stay out of trouble with the FAA, and avoid hurting any people or property.  My launch was out in the middle of the dessert.

Whether or not you’re interested in rocketry, I hope you learned something new, or were inspired in some way by my experiences.

For all my friends and followers in different countries who don’t have access to these materials but still want to build rockets, watch for my matchbox rocket video coming next week.  I promise you’ll be able to build this next kind. :)

Redneck Rocketry

        真正的火箭在過MaxQ之後受空氣的影響就會越來越小，但那好歹也是在數十公里的高空，業餘火箭要是真能飛上那個高度……飛上去之前大概人會先被國家安全勢力關切吧，大多數的火箭還是在低空的稠密大氣下飛行的。對沒有任何主動控制能力的火箭來說，想要穩定飛行就必須保證火箭整體是氣動穩定的，也就是說
