***PRE-FLIGHT PROCEDURES***

THE ROCKETEER WILL:

• Construct the rocket using adequate levels of craftsmanship and materials;
• Perform calculations and/or simulations to assure performance for the given flight configuration to assure proper CP (Center Of Pressure) to CG (Center of Gravity) relationship for the given flight configuration. This is only necessary for scratch-built rockets or modified kits;
• Have the CP and CG marked on the rocket (not necessary for unmodified kits);
• Properly select, assemble and install the motor;
• Test any electronics used in the recovery system;
• Ground test the recovery system – perform live ejection charge tests for the given flight configuration and any time the rocket configuration is changed;
• Fill out a launch card;
• Present himself/herself and the rocket to be flown at the RSO table when ready to fly;
• Execute the RSO’s preflight procedure – SEE/REF RSO CHECKLIST;
• Be prepared to answer any questions the RSO may have about the rocket at the preflight safety check;
• Fill out the launch log;
• Confirm the pad and personnel positions are correct in relation to the projected flight path;
• In coordination with and approval from the LCO proceed to pad and ready rocket to fly;
• Confirm launch rod/rail alignment is correct for conditions;
• Arm and confirm flight electronics after rocket is upright on rail;
• Install igniter after electronics armed and rocket on rail (not required for most model rockets);
• Arm pad launch circuit;
• Upon approval from the LCO, proceed to launch the rocket;
• Perform range and sky checks at T-Minus 30 seconds;
• Perform final range and sky check at T-Minus 10 seconds;
• Arm launch controller at T-Minus 10 seconds;
• Begin Countdown at T–Minus 5 seconds;
• Start ignition at T– Minus 1 second;

 

THE RSO WILL:
At the RSO table;

• Physically inspect the rocket for construction integrity
• Assure CG and CP are marked on the rocket
• Inspect the recovery system; shock cord, hardware, and parachute
• Ask the rocketeer about the motor;  proper selection, proper loading/construction process
• Perform CG check
• Ask any questions the RSO deems prudent
• Check the rocketeer’s launch card and fill out appropriate parts
• Ascertain the rocketeer understands launch process and range  safety procedures
• Assure launch pad alignment is safe for given wind conditions and personnel location
• Communicate a GO/NO GO to the Launch Controller
• In coordination with the LCO, assign a launch pad

 THE LAUNCH CONTROLLER WILL:

• Alert all personnel that a launch is imminent
• Assure recovery personnel are at standby Perform a sky check
• Perform a range clear check
• Work with rocketeer to perform the launch

EVERYBODY WILL:

• PAY ATTENTION WHILE LAUNCH OPERATIONS ARE ONGOING!
• Act as safety monitors – safety is EVERYBODYs business – call “KNOCK IT OFF” if you see a safety issue
• Assist in tracking the rocket upon launch
• Follow the directions of the RSO and LCO

 

IF ANY OF THE PRECEDING CONDITIONS ARE NOT MET  – THE ROCKET WILL NOT FLY UNTIL THE DISCREPANCIES ARE CORRECTED AND THE RSO RE-INSPECTS AND APPROVES FOR FLIGHT!

Rocket Flight Log by Scott Young is a great program for helping to keep track of your kits.  For $11.97 its a great deal.  It helps with recording flight logs, construction notes, photos, rocket profiles and costs.

One interesting person from the past is Ray Dunakin.

Aerial rocket photography is neat.

I helped by contributing a little bit of money for this school to complete its project back in 1994 and this is something that any engineering department in High school could accomplish.

Robert Crippen was a neighbor of mine where I grew up and the space shuttle is a program that should have never been canceled.

A free program for designing your own rocket is called Open Rocket.

Here is a good link that talks about the program:

The three day class was very fun and educational.  Seventeen students were present on the first day of class.  The first hour covered safety.  Then the next two hours went over the beginning of building the Estes Viking rocket kit.  We first assembled the shock cord mount, and then attached the fins to the body tubes, launch lug and engine block.  At this point we stopped for the day.

On the second day, we continued with completing the building of everyone’s rocket kit.  We even set up an area where each participant could spray paint their rocket if they wanted to.  During the last hour of the second day’s class, I brought out the multiple launch control system and went over the launch procedures.  I addressed who the Range Safety Officer would be and what their responsibilities involved. Then I went over the Launch Control Officers duties.

On the third day (launch Day) the weather was just right.  We had a mild breeze of a 7 mile per hour wind coming from the west.  We were having a Spot landing contest and everyone did a great job.  The closest distance from the target was 73 feet.  Everyone was able to launch their rocket twice with an Estes A8-3 motor.  Two competitors had their rockets land in a tree.  They were given a new kit to build at home, since their rockets were not able to be retrieved.

I hope that we will have more classes offered similar to this one by the Parks and Recreation department again.

I would like to start working on a newsletter similar to the one here.  This was a current newsletter put together by a club in Southern California that I would frequently attend.

I look forward to the next launch day

Hope to see others out there
