SLRA Buder Park launch, March 30 2024

(Flew Purple Motor Eater for the first time, have a photo)

Airfest 30, August 30 - September 2 2024, Argonia KS

I went to Argonia for the first time in a few years to fly Peregrine, the 3" minimum-diameter rocket I had been working on all year. Simulations put it between 30,000 and 35,000 feet AGL.

Peregrine flight #1, M685

Weather conditions: sunny; wind N @ 9 mph, 88 F, 34% RH

Wildman Mach Three “Peregrine” flight #1:
Launch time: Saturday, August 31, 2024, 12:15 pm
Weather conditions: sunny; wind N @ 9 mph, 88 F, 34% RH
Motor: AeroTech M685W-PS White Lightning Moonburner
Max altitude: 23248 feet AGL (TeleMega, GPS), 22060 feet AGL (TeleMega, barometric), 22008 feet AGL (EasyMini, barometric)
Max velocity: 1451 ft/sec (989 mph, Mach 1.3) (TeleMega, accelerometer)
Max acceleration: 13 G (TeleMega, accelerometer)

(Peregrine narrative goes here)

GPS track (viewable with Google Earth)

Raw flight data from TeleMega (viewable with AltOS)

Raw flight data from EasyMini (viewable with AltOS)

  • A rocket leaving pad 86 at Argonia with a bright white exhaust and a large plume of white smoke. A fly-away rail guide can be seen detaching from the rocket.
    Peregrine launch, seen from pad camera.
  • A map showing Peregrine's apogee about 5 miles ESE of the launch site, then drifting back under parachute to a spot about 3 miles SE of the launch site.
    Ground track of Peregrine's flight.
  • A screenshot of Google Earth showing the rocket boosting at a significant angle off vertical.
    Peregrine's flight path shown in Google Earth.
  • Statistics for Peregrine's flight - notably, 22974 feet AGL, Mach 1.3, 13 G maximum acceleration, and 1856 seconds (about 31 minutes) flight time.
    Statistics for Peregrine's flight.
  • White fiberglass fins attached to a red fiberglass body tube, with black (ProLine) fillets.
    Initial attachment of fins with fillets.
  • From the inside of the body tube, showing the footprint of the fillets showing through.
    The fins' "footprint" on the tube.
  • A paper fin template next to a piece of fiberglass fabric cut to the same shape.
    Cutting fabric for the tip-to-tip layup.
  • Two photos of a drop of water on one of the fiberglass fins. In the top photo, the water is beaded up into a taller, rounder drop; in the bottom, the water has spread out showing that the surface is rough enough to break the water's surface tension.
    Doing a water-break test to show when the surface was rough enough for layup.
  • The Peregrine rocket in a plastic and wood fin jig, with the fins resting on wood planks wrapped with wax paper.
    Fin jig constructed for the layup.
  • Same setup as the previous photo, with gallon ziploc bags of water on top of the fins.
    First layup; bags of water are used to press down on the peel ply.
  • Fins with cured fiberglass tip-to-tip layup.
    First layup after curing.
  • Closeup of the layup on a fin showing that the fabric was not pressed down fully to the surface.
    Layup after trimming; adhesion was poor in spots, as shown.
  • TeleMega and EasyMini boards attached to a 3D printed sled and partially wired.
    "Back" side of sled with the TeleMega, EasyMini and pin switches.
  • An orange action camera and two LiPo batteries attached to the other side of the sled.
    "Front" side of sled with the RunCam and two LiPo batteries.
  • A red fiberglass coupler with a circular hole in the switch band, behind which is the lens of the camera previously shown.
    The sled inside the coupler, showing the port hole for the camera.
