HARA Newsletter – March 2013

Test what you fly, and fly what you test”

Thursday night’s meeting was another success.  Attendance has been up 3 fold and the new focus of the meetings on helping people grow in hobby rocketry and show off their projects seems to be resonating rather well.  I gave a 45 minute presentation on dual deployment recovery systems in our first in a series of Tech Talks that cover lots rocket building techniques.   Read more

“We Are On Ascent” ~ Vince Huegele

 

Thank you everyone for coming to the meeting last night. We had a great turn out with nearly 30 people in attendance and a lot of new faces. We kicked off the meeting with our guest speaker and a few pizzas.  Mr. Chuck Pierce who is branch chief of Spacecraft Propulsion Systems at MSFC and has a rich background with space shuttle and hypergolic propulsion systems, shared with us the propulsion research being done here in Huntsville.  Mr. Pierce brought along a space shuttle reaction control motor to show off.

HARA Launch at Lincoln

By Vince Huegele

We don’t get many requests for launch demonstrations after Thanksgiving, but that’s when Lincoln Academy called us to help them with their Spaceweek. They had heard there was a rocket club in town and found our website. Read more

Estes on steroids

by Bill Cooke

Mention Estes to a rocketeer these days, and you usually get a smirk; they are famous for Ready-To-Fly (RTF) and other easily built low power kits. Not much thrill to many in flying birds using 13 mm, 18mm, and 24 mm motors (1/4 A to E impulse). But that’s changing…  Read more

Rocket Design/Simulation Programs for TARC

by Bill Cooke

TARC is like the real world of rocket design in that the teams must resort to design/simulation software to help flesh out the initial concept, making sure it can meet the goals before pressing on to actual construction/testing. Here the vendors have come to the rescue in providing three outstanding packages, any one of which can be used to design a winning TARC entry. Read more

Thoughts on the 2013 TARC challenge

by Bill Cooke

NAR and the AIAA have just released the objectives for the 2013 TARC season. In brief, they are

  1. Altitude mark of 750 feet
  2. Flight Duration of 48-50 seconds
  3. 15″ parachute must be used to recover the egg and the altimeter
  4. Egg must be placed horizontally (“lying on its back”)
  5. Section of rocket containing the egg must be at least 60 mm (2.362″) in diameter
  6. Gross liftoff weight of under 650 grams
  7. Motor impulse must be 80 newton-seconds or less

At first glance. this seems simple; after all, each of these has been used in past years. No surprises, so pretty easy challenge for the TARC teams, right? Read more

Pack 351 Rocket Blast – and indeed it was!

by Bill Cooke

Every year Cub Scout Pack 351 has their annual ‘rocket blast’, in which the cubs fly rockets they have recently bought or built. HARA – in the form of Chuck Pierce and various others who show up to assist – always provides the launch setup and range control, which has been fairly easy for the past couple of years due to the use of the USSRC/Space Camp launch facilities.

HARA’s School Launches

by Vince Huegele

As the 2012 school year winds down HARA has been busy with launch demonstrations. On May 3 we were set to fly for the 4-H Urban Youth Farm Day at the A&M field in Hazel Green, but steady showers scrubbed the launch. The facility has a building that could hold all 300 kids so 4-H held the event inside. Read more

Building Rockets, Finale – Decals

By Bill Cooke

A lot of the new rockets come with “peel ‘n stick” stickers these days, rather than decals. Many rocketeers call these “peel ‘n cuss”, because they are not much fun to apply (especially roll patterns and long names) due to their stickiness – very little room to make a mistake. Read more
