- 2nd attempt of the Cesaroni N5800 minimum diameter rocket project
There has not been that many successes on 4" minimum diameter rockets on commercial N motors...
Goal:
1) Has to be minimum diameter on Cesaroni N5800
2) Wanted to use frangible metals for fins, tubes, and nose cone (aluminum)
3) Ensure rocket does not shred
4) Recovery Safely
5) Get multiple flight data points
6) Get GPS data
7) Get video data
8) Paint it to cool sorta cool
9) High altitude/speed and surpassing the current TRA record of 44,623 ft
Was able to achieve 8 out of the 9 goals. Did not set the record but everything else worked perfectly!
4" Min Diameter Rocket
110" tall
Nothing protruding from rocket besides fin can, rail buttons, and shear pins (recessed switches)
1515 launch pad
Motor Cesaroni N5800 (20,146N-S)
Altitude 30,000ft (using Rocksim, with wind, temp and proper elevation)
Speed Mach 2.5 (2790fps) (1902mph)
36 seconds to apogee
Conventional rattle can spray paint
55lbs loaded
23lb vehicle
All aluminum
Guy Hardy Fin Can and Nose Cone (5:1 conical with metal tip, not fine point)
Bolt up fin can (brackets permanently bolted to aluminum tube and fins permanently bolted to brackets, then cut outs to see motor case to look cool and cut a little weight)
Nose cone shoulder aluminum, nose cone tip aluminum with plywood and fiberglass in the middle for GPS/Transmitter Antennae)
Aluminum Upper Tube
Nose Cone houses GPS and Camera
Avionics Bay (bolted to motor case forward closure) houses the separating charges
Perfectflite altimeter (free, thanks Perfectflite)
Marsa54, 50G
AIM XTRA GPS for altitude verification and tracking
CSI Radio Frequency Tracker
GO Pro Hero 3 (in nose cone)
Suppose to be Dual Deployment, single compartment -- nose cone
3 of 4-40 shear pins (115lb force to hold nose cone in), used small vent hold to relieve pressure in parachute compartment.
Rouse Tech CD3 Co2 at 25gram charge (equivalent to 5gram back power charge)
Backed up by 3.5gram black power charge
Co2 worked, then black power is negated (by servo disconnector switch)
Co2 and black powder are in front of main chute attached to shock cored (zip ties and tape)
36" Sky Angle Classic 2 parachute for drogue
AARD was supposed to hold in main Chute to 3500ft but pulled apart at apogee.
Single cord from drogue to main @ 30ft of 9/16" tubular Kevlar
Sky Angle Cert 3 -- Large main chute (35 fps under main)
Landed 4.25 miles away
Pulled 30g's off the pad and held!
Total flight time ~16 minutes
Rocket Named after my Girlfriend as "she is one tough pill to swallow"
Flying conditions
30,000ft altitude
Outside air temperature at that altitude: -40degF
Wind Speeds at that altitude: 40 mph
Great job! Congratulations! I am going to be starting my Level 1 certification process soon. I've been flying Estes for 45 years. It's time!
Awesome flight!!! Great job! Text book for sure!
Wow - bragging rights for sure on that flight. Great job!
Totally Cool - love those in-flight videos people are getting these days. Very cool rocket indeed!!
This is great...what a speed!!!
wow man your rockets are super fast !! good job !!
Nice launch Gerald...
This is the most amazing video I saw !!!!!
omg that rocket is moving
Great job on the video, even better it's great your girlfriend is so supportive. Your rocket is gorgeous! I like the picture of the girl on there. Beautiful flight! Love the slow motion. Nice work!
more cut aways and camera changes than a lethal weapon fight scene.
Well done!
Great Video
AWESOME KEEP UP THE GOOD WORK
very impressive FCC ret USN..
very nice
Awesome!!!
some day i will be out there with you all
Very cool. Now make a two stage rocket.
Great flight! Good work! Why was it spinning if you used a fin can?
Just watched this video for the first time here in 2020. Wondering if there has been another attempt made by this crew and whether they worked out why they weren't able to get to their target altitude.
I'm sharing and will be picking your brain in the future. :-)
Wow!!!.........what elce can I say. = )
Was that a plane I saw in one of the ground shot slow motion video? If so, that's a no no
the video looks sped up at 1:55 and 2:08.
That thing is FAST!
lol no man this guy makes some of the fastest rockets out there .. this is not sped up thats how fast they are really going
Did you film a UFO at 2:13?
Where did you buy This rocket ? I want that kit bro
Flew a min diameter 75mm rocket 56k ft mach 2.7
Got any fast rockets?
how the hell did it accelerate so fast? what type of motor was it?
are you illiterate?
N5800 average thrust 5800N or 600kgf
howd you get a perfect flight altimeter for free?
Anyone know this guy’s email or how to contact him?
Can somebody tell me the best camera equipment for filming the flight of the rocket, (onboard).
i guess go pro or sony action cam, but make sure you secure it properly
