Flight Log - 2015-11-14 - Matthew Bond's 2.70x Upscale Wolverine

An upscale of the classic Estes Wolverine based on standard LOC 2.63" tubing.  Rocket has a 29mm motor mount with an AeroPac retainer.  Fins are made from 1/8" plywood, with the main fins being TTW to the motor mount.  Nose cone was constructed from an ogive balsa cone with the distinctive canopy carved from a separate balsa block.  Recovery system uses a 1/8" flat woven Kevlar shock cord epoxied to the motor mount and tied to a large screw eye in the nose cone shoulder.  Either a 24" or 30" spherachute is used based on the field conditions.  Rocket is finished in a silver metallic paint with the usual outstanding vinyl decals provided by StickerShock.

First visit to the NEFAR launch field near Bunnell, FL for their annual 2 day launch.  A series of farm fields divided by tree lines, roads and irrigation ditches, fairly open, but not completely free of recovery hazards.  Wind was blowing pretty good both days.  On Saturday winds varied between 15 and 20 mph, blowing straight out from the flight line.  Unfortunately this caused many flights to arc back over the flight line.  There were many smaller rockets that landed among the parked cars and at least one large (10" diameter) rocket that came in ballistic near the end of the flight line.  I ended up flying mostly small stuff since I wasn't familiar with the field and the winds were not favorable.

The upscale Wolverine ended up being the largest rocket I flew all day.  Very abnormal boost for this bird, corkscrewing severely off the rod, still travelling more or less in an upward direction.  Very low apogee, rocket fell flat for a bit, then nosed over and started acceleration before the ejection charge finally went off.  The chute deployed normally and the rocket landed on the field a short distance behind the high power pads.  There was no damage to the rocket and the motor seemed to have burned nominally.  I suspect that one of the "wings" of the rocket had gotten hung up on the large diameter composite material blast deflector being used on the pad.  The deflector edges were fairly rough so I believe it just caught the fin, putting some serious torque on the rod/pad/rocket before it broke free.  Unusual, but in the end non-threatening.
