Two more bonus Artemis missions

(July 10, 2010 mission update)

OK…We’ve had some bonus missions, and haven’t had much advanced warning to post about them on the website, so this is a catchup post…

July 3rd 2010 – Pichman’s Farm

Artemis Booster #1 (Big Red) had a bonus mission on July3rd.  There was no flight agenda for this rocket, and we were thinking a series of pre-night launches would be a great way to retire the rocket, and place it in our rocketry museum.   ALS024, 25, and 26 were planned.

ALS024 lifted off for a perfect flight to 600 feet, and parachute deployment.  At about 45 feet from the ground, Big Red was snagged in a tree…and it is still stuck there as of this writing.   Needless to say, planned “fun” missions ALS 25, and 26 were cancelled, and re-assigned to the next missions.

July 10, 2010 – Harmon Flying Field

Another bonus day, so we quickly lined up a mission consisting of four flights on two different Artemis Boosters, #2 and #3.

Both boosters were testing changes to the ejection baffle system.  Booster #3 was flying a new heat shield for the ejection baffle that is much sturdier (and lighter) than the system we’ve been using.   Booster #2 was testing the same heat shield PLUS some changes to the inner baffle designed to make cleanup of the system easier.

In addition to the heat shield, Artemis booster #3 was also assigned with the task of flying the first “full load” launch.  We loaded the payload bay with a 9 volt battery, which is almost the heaviest weight the rocket will ever fly.  Liftoff weight in this configuration is 11.9 oz.  Two flights were planned.  ALS025 and ALS027.

The engine chosen for these flights was the Aerotech E15 “White Lightning”.   Liftoff was flawless, and the rocket carried its payload to around 1500 feet.  Deployment was on the money, and to everyone’s amusement, the rocket deployed its chute right in the middle of a thermal.  The rocket “hung” in the same place for a few seconds before decending.  The rocket encountered two more thermals on the way down.   The rocket finally landed about 850 feet downrange from the launch pad.

Mission ALS025 is underway launching on an E15W

It’s second flight – Mission ALS027 – was also flawless using same configuration as ALS025 except for a small passenger…a four leaf clover MTMA president Mark Recktenwald found growing near the launch control tent.  We loaded this “passenger” in the payload compartment, and “let ‘er rip”.   The rocket was recovered about 1200 feet downrange.

Booster #2 also had two missions.  It’s flight agenda was to test the full list changes to the ejection baffle system.  If these changes proved successful they should greatly simplify the “turn around” process needed to return individual Artemis boosters to flight ready status.  The end result was the new baffle system met — and greatly exceeded expectations.

The next four pictures of mission ALS028 are a cool record in still frames of the launch / flight…

July 10th ended with the Artemis program clearing two major milestones.  A great way to put July 3rd behind us!

Next Artemis launch window will be announced soon.

Artemis Bonus Missions!

(Harmon Flying Field, June 26, 2010)

Artemis booster #2 was flown twice in its “Artemis V” configuration.

These flights were just a couple of fun sport flights…there was no particular “mission agenda” — just having fun with a bonus day of rocket flying before the month long break in rocket flights.

These Artemis flights are tagged “ALS-022 and ALS-023″.  Rocket flew great — winds were gusty,  so we were flying in between wind gusts.  Flight ALS-023 was on “hold” for several minutes before launching as sustained winds were higher than what the booster was designed to handle.  We flew “right on the edge” of the safety margin, and the booster performed well — with quite a bit of weather-cocking after about a 150 feet in the air as a result of higher wind speeds above that height.

There is  a short video of this flight.  You can watch it below…

Pegasus MKII maiden flights a success

(Harmon Flying Field – June 26, 2010)

A week after the last flight of the original Pegasus booster, the Pegasus booster MKII with its structural improvements took its maiden voyage earlier today on a C11-3 motor.  Two flights were done on the C-11, reaching an altitude of about 450 feet.  After two successful flights on the lower power engine, the new Pegasus spread its wings and climbed to about 1000 feet on its full power D12-5 engine.   No structural issues were noted, and its improved baffle system performed as expected.  The next flight of the new Pegasus booster will be in August.

I did not get to take any launch pictures, so some post-flight pics will have to do…

The only real design tweak this time around will involve painting the Ejection baffle system to assist in cleanup readiness procedures for quicker turnaround between launches.

July 3rd Artemis night launch cancelled; Pegasus flight is on!

Jun24

Posted In: XR2 (Artemis) Medium power booster Project, XR3 (Pegasus) High Performance Booster

The Planned night launch has been canceled due to a conflict in my schedule.  Will shoot for an evening launch this coming “Patriot Day”, September 11th.

There were several launches of Artemis boosters # 2 and #4 last Friday, June 18th at Streetsboro City Park as part of their night movie in the park  presentation “Planet 51”.   I was there with the rockets along with other members of MTMA and the Skybusters rocket clubs.   The last night of the evening was at 8:45PM as Artemis booster #2 streaked into the dusk sky for a spectacular liftoff, and perfect landing.   It was a lot of fun.

Next launch is set for project Pegasus, with the Pegasus MKII making a few test flights at Harmon field June 26th.  Should be a lot of fun!

The purpose of this next test flight is to test the ability of the new MKII airframe design to withstand the moments of maximum dynamic pressure, which caused structural damage to the first booster after its flight at the Streetsboro park demonstration flights.   The booster functioned normally aside from a momentary “dip” in its flight trajectory– which was the moment the airframe was damaged as the rocket was under maximum aerodynamic stress.

We will report how the test flight goes!

Pegasus booster makes its maiden voyages…

(Sunday, June 13th, 2010 Harmon Flying field – Aurora, Ohio.)

It wasn’t a planned mission, but a good friend of mine in the hobby, Andrew, convinced me to let her fly.   The Pegasus project wasn’t meant to take to the sky until sometime later next month – if not later in August.

I brought the new rocket by on day #2 of the MTMA club launches for a show and tell session on the project slowly born from the leftover parts of the Artemis launch vehicle project.  The idea behind Pegasus is to design a rocket with all the high speed / high altitude performance of project Aquila – only much better all around.

Pegasus is much lighter & stronger than Aquila or Artemis (for its size), and is built for speeds beyond Mach 1, should I ever feel bold enough to put her up that high.

The first three flights were pretty breathtaking, and it took three tries to finally catch the thing in a photograph!

There is no paint on the rocket yet…in fact, the glue had *just* enough time to dry on the main airframe before we decided to send her up.  All three flights were flown on a D12-5, and the altitude all three times were well in excess of 1,000 feet.

As I stated earlier, the Pegasus booster was barely done.  There wasn’t even a launch lug on the rocket.  Good ‘ol Andrew exclaimed “Not a problem, we have a rail launcher set up!”   So the rocket was launched from one of those.

This bonus day of flights was great, and we got to see our newest rocket take to the sky!
