OcktoByte Posted May 16, 2017 Share Posted May 16, 2017 Team Name: Preston Rockets Available Funds: 30,000 Vehicle Name: RickRock Mk. 1 Parts and Costs: S1 SRB-KD25K "Kickback" Solid Fuel Booster (2700) -50% = $1350 Mk. 1 Command Pod ($600) Mk. 16 Parachute ($422) Heat Shield (1.25m) ($300) TR-18A Stack Decoupler ($400) AD-R8 Winglet (640) x3 = $1920 Total: $4,992 Design Goals: Vehicle is designed to reach 50km manned and land safely. Launch Goal: Successful liftoff and ascent from the ground. Safe return to surface after reaching 50km. Pilot Plan: Reach 50m at 90 degree angle, then tilt to 75 degrees, decouple thruster when out of fuel, ready parachute. Illustrations: Post Flight Briefing Preston Rockets Launch Time: 10:56 Team: Sean - Pilot Nisa - Reporter Nathan Justin Play by play: Launched rocket straight up tilted to a 70 degree angle at 100 meters continued ascending until 50km, when we detached thrusters reached a max height of 120000km began descent, overheated, and parachute burned up and crashed Screenshots: Time of Flight: 23 Minutes Summary: In our first launch we hoped to reach our first goal, a height of 50km, and were successful in this part of our plan. We reached a maximum height of 120,000km but upon reentry burned out our parachute and were unable to land safely, killing a Kerbal. In our next launch we will alter our flight path by easing into a smaller angle at a slower rate. additionally we will remodel our rocket to have more stability. Opportunities/Learnings: Angles matter significantly, need thrusters to counteract acceleration back into atmosphere Strategies/ Project Timeline: Financial Loss, a learning experience, will put more effort and research into next launch Milestone Awards Presented: None Obituary: A Reminiscent Haiku Upon re-entry, Valentina Kerman died. Parachute perished. Quote Link to comment Share on other sites More sharing options...

Using more parachutes and altering flight plan. Launch Goal: To have successful launch and landing after reaching 50km. Pilot Plan: Upward ascent to 50 m/s and begin tilting to 70 degrees, First decouple at 15km, Second decouple at 40km, Launched parachutes just over 400 m/s Screenshots: Post Flight Briefing #2 Preston Rockets Launch Time: 10:59 Team: Nate-Pilot Nisa Nathan Justin Play by Play: Launched first stage and began tilt to 70 degrees @ 15km First decouple when furl ran out Second decouple at 35km Max Height at 126km Began descent Deployed parachutes at about 400m/s Time of Flight: 29 minutes Summary: Our rocket was able to reach our goal of 50km, and landed safely. we reached a max height at 126km, and deployed parachutes at a speed of 400m/s, which allowed us to land safely. for our next flight, we would like to build a new rocket in order to enter orbit. Awards collected: award for reaching 10km, award for reaching 10 km manned, and award for reaching 50km manned Screenshots: Quote Link to comment Share on other sites More sharing options...

The launch goals we are hoping to achieve with this launch are achieving orbit and preforming an EVA. Pilot Plan: Fly at 90 degrees until velocity reaches 60 m/s, then begin turning slowly to 10 degrees. Once apoapis reaches over 80 km, cut engines and set maneuver to orbit Kerbin. Once stable orbit is achieved, perform short EVA outside of ship. Quote Link to comment Share on other sites More sharing options...
OcktoByte Posted May 30, 2017 Author Share Posted May 30, 2017 Post-Flight: Launch Time: 10:50 Play-by-Play: Rocket was able to escape the atmosphere. While ascent was shaky, stable orbit was achieved. A short EVA was performed once orbit was achieved. Photographs: Time-of-Flight: 0y, 0d, 00:07:30 Summary: The mission was a success. We achieved stable manned orbit, and performed an EVA. We faced the challenges of finding the correct angle to launch at in order to achieve our orbit, setting our course, and using thrust at the correct times. Opportunities / Learnings: The team learned that our momentum will carry us even if not using thrust, and how to use maneuvers to achieve the correct path. Strategies / Project Timeline: Achieving these goals gives us the funds to create larger rockets to reach further milestones Milestone Awards Presented: Achieving Stable Orbit - $40,000 Achieving Stable Manned Orbit - $50,000 First Kerbal EVA - $60,000 Available Funds: $221,779 Quote Link to comment Share on other sites More sharing options...

OcktoByte Posted June 5, 2017 Author Share Posted June 5, 2017 Preston Rockets $221,779 Sat-orb 999 Parts List: Gigantor XL Solar Array x2 = $6000 M-Beam 200 I-Beam = $25 Modular Girder Adapter = $50 AE-FF1 Airstream Protective Shell (1.25m) = $300 RC-001S = $2250 TR-18A Stack Decoupler x2 = $800 FL-T800 Fuel Tank = $800 FL-T400 Fuel Tank x3 = $1500 LV-T45 "Swivel" Liquid Fuel Engine -50% = $600 AV-R8 Winglet x4 = $2560 CR-7 R.A.P.I.E.R. Engine -50% = $3000 TT-38K Radial Decoupler x2 = $1200 BACC "Thumper" Solid Fuel Booster x2 -50% = $850 Aerodynamic Nose Cone x2 = $480 Z-1K Rechargeable Battery Bank x2 = 1760 Design Goals: This rocket is a modified version of our Copycat Mk. 2 meant to put a satellite into orbit. The thrusters have been upgraded to account for the increased mass of the payload. Launch Goals: We plan to get a remote controlled satellite into orbit around Kerbin. Pilot Plan: Similarly to our Copycat, we plan to use our solid fuel boosters to accelerate upwards, beginning to turn towards a 10 degree angle. We plan to detach the solid fuel boosters once they run out of fuel, and stage our main engine off once it runs out. Afterwards, our secondary thruster will allow us to reach a height allowing us to maneuver into orbit. Quote Link to comment Share on other sites More sharing options...
OcktoByte Posted June 5, 2017 Author Share Posted June 5, 2017 Post-Flight Launch Report Launch Time: 10:40 Members Present: Sean Preston, Justin Diehl, Nathan Kenney Play-By-Play: Used solid and liquid fuel boosters straight upwards until the rocket reached 60m/s, escaped atmosphere at around 10 degrees from horizontal, achieved orbit, and activated solar panels. Photographs: Time of Flight: 8m, 5s Summary: We were able to launch a satellite into orbit around Kerbin. Our rocket performed as expected. Opportunities / Learning: How to account for center of mass and weight of rocket components. Strategies: This achievement allows us more room to construct bigger and better rockets, including the possibility of a lunar mission.
