Parachute Recovery Systems Design Manual by T W Knacke

Download Free online or purchase a printed copy!

The Parachute Recovery Systems Design Manual by Theo W. Knacke is the design standard for parachutes.  More than you need for rocketry but a great resource.

Originally printed in 1991 on contract to the US Naval Weapons Center at China Lake, CA, this book now approved for public release from the US Navy and is available free for download direct from their site.

Tim MacLeod's Level 1 Certification

Congratulation to Tim MacLeod on his successful Level 1 flight yesterday, Saturday August 28, 2010 at the NAPAS launch. Tim is the designer of many Sunward rocket kits, including the Mercury Lander Jr, the Solar Eclipse, and many others.

Finally got his certification as he has been waiting almost 2 years for the flight.  He waited because of weather, too windy, scared to lose the rocket, etc.

Upscale SkyBender

Courtesy of Dale Marshall, today I present his upscale SkyBender.

According to Dale:

It launched great under three D12 engines but failed under three C11s (parachute didn't deploy).....  The plans are very similar to the Skybender. ...Iit was fun to build and very fun to fly.

I have attached his rocksim file. (right click to download)

Certification Videos

Finally I am able to add videos for the Certification Flight.

This first video is just basic information as there was a continuity problem. Each video is about 2MB in size.

The second video is of the actual flight.  After a while, the rocket can't be seen in the video. Sorry about the finger on the image. Tim MacLeod is the voice in the background.

Nose Cone Production Results

Attached are some images of a production run of Balsa Nose Cones.  In the pile are BT56, BT70, and BT80.  Still to be doine are BT60 nose cones.

The BT56 are a custom size for bulk school packs.  They are not currently listed on the web site.

Lots of saw dust.  I next plan to control the dust on the CNC machine, mainly by enclosing the unit as much as possible and attaching a dust collector.

CAR-ACF Level 2 Certification Flight

Well, I launched the rocket on Saturday June 19, 2010.  Successful launch and recovery!  Thanks to Bob, Chris, and Jim of NAPAS for certifying the launch.

The expected height was 2,200 feet but it seemed to go higher.  With a little wind (about 16km/h), and the ejection charge set too low (4 seconds), the rocket drifted about 1 1/2 km downrange!  Nice walk there and back though tall grass, swamps, and fences.  It does help to read the instructions for the motor before using it.

The rocket flew on a Pro38 382-I-170-14A Classic high power motor.

CAR-ACF Level 2 Certification

I have enclosed 2 pictures of a rocket that I built for my  Canadian Association of Rocketry  - L'Association Canadienne De Fuséologie Level 2 Certification test.  This  test is based on a successful construction, flight, and recovery of an "I" motor based rocket.

The kit is an old kit that has been around and missing some parts.  Large at 5 3/8" (sorry, Sunward doesn't have these just yet) and a height of 37".  Being a wide rocket, hopefully it won't go as high and I won't have to go far to recover it.
