Default HARA and LOFT-1

The tech talk at the March club meeting was by Wayne McCain, a former HARA member from way, way back. His topic was the first commercial launch (with a paying customer) from Canaveral Air Force Station, one in which a couple of HARA members (he and Matt Steele) played prominent roles. The rocket was a LOFT-1 (Launch Operations Flight Test), a 10 foot, 6.1 inch diameter vehicle powered by a N5000 motor developed by Vulcan Systems. Imagine - a N class motor back in 1988! Actually, there were three of these beasties made, but the ATF confiscated two when regulations set in - their fate is unknown, but it is probable they were destroyed. Anyway, here is Mr. McCain's talk (about 30 minutes in length):

LOFT-1 talk on YouTube

Inspired by the talk, I gathered together the available data - which wasn't much - on LOFT-1, and concocted an 18 mm BT-55-based downscale in OpenRocket. It looks like I have another entry on the build list :/

Matt, do you have any other details on this rocket?

Buried away, I have some info, but I am not sure where it is at.

The one we flew was pretty impressive; this was long before N motors were commonly flown. We flew it out at Hartsell, CO at the LDRS field. This was long before there were certification levels. for high power.

There were two production versions - there was a set of two that were delivered and then set aside; and then a third one that was actually flown from the Cape.

IIRC, they were 6" in diameter, 10' long, and weighed 81 lbs, powered by a Vulcan Systems N3500 with dual pyrotechnic delays. The motors had 23 lbs of propellant in them.

If I stumble along on any more info, I'll post it.

Matt
