Peregrine is built from a Wildman Mach 3 kit (75mm minimum diameter) and am planning for a launch at Airfest 2024. The flight will be on an AeroTech M685 motor and should exceed 30,000 feet AGL (preliminary simulations are showing 34k-35k). Construction took place between February and August 2024.

  • 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.
  • Screenshot of OpenRocket showing a basic design for a 3 inch minimum diameter rocket with 4 fins.
    Peregrine design in OpenRocket.
  • 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.
  • The sled previously shown, with additional wiring and the TeleGPS antenna taped down to a piece of clear plastic with red electrical tape.
    The sled with completed wiring and lexan antenna support.
  • The rocket painted gray with a yellow nose cone.
    Painted.
  • The rocket with yellow letters spelling "peregrine" in all caps, and yellow stripes on the fins.
    Graphics applied.
  • Peregrine on launch pad with a large "86" sign behind it. The sky is partly cloudy.
    On the pad, waiting for a break in the clouds.
