MPC (1969-1973) parts file for OpenRocket
|
|
|
|
by Dave Cook NAR 21953 caveduck17@gmail.com 2014-2017
|
|
|
|
This file contains everything from the 1969 Catalog 1, 1970 Catalog 2, and the 1973 Minirocs catalog.
|
|
The original vendor data is very incomplete; various minor dimensions have been estimated, usually with
|
|
reasonable justification.
|
|
|
|
MPC did not give the weight of anything, so I have used standard densities for paper tubes, balsa, and
|
|
styrene, along with an estimate for thickness of the plastic parts.
|
|
|
|
I recovered data about centering rings, stage couplers, and a couple of nose cones by reading kit instructions
|
|
and kit descriptions from the catalogs, even though the parts were never listed, and the kit instructions
|
|
don't give stock numbers (and usually not sizes) for any of the parts in the kit.
|
|
|
|
There are two plastic nose cone assemblies known to exist that are not listed because we have neither the
|
|
lengths nor the weights:
|
|
|
|
1) The plastic space capsule used in the Moon Go. This is a 3-piece unit; see Moon Go instructions on
|
|
plans.rocketshoppe.org
|
|
2) The 2 piece plastic Martian Patrol nose cone, which was a double taper cone. Approximate dimensions could
|
|
be obtained by photogrammetry of the Martian Patrol instructions drawing.

to be 70mm (2.75") long, OD=19.0mm, ID=18.0 mm.

<!-- Balsa Nose Cones -->
|
|
<!-- Nose cone shapes:
|
|
I obtained the nose cone fineness ratios by photogrammetry of the shape reference
|
|
drawings in 1970 Catalog 2 from the vintagevendingwarehouse.weebly.com site. The images
|
|
are low res but usable. Values are as follows:
|
|
Shape A: Base diam 22.0 px, length 88.0 px, shoulder len 10.8 px => Ogive 4.0:1,
|
|
shoulder len = .50 * diam
|
|
Shape B: Base diam 23.0 px, len 31.1 px, shoulder len 12.0 px => Ogive 1.35:1
|
|
shoulder len = .50 * diam
|
|
Shape C: Base diam 22.4 px, len 87.9 px, shoulder len 12.2 px => cone (rounded tip) 3.9:1
|
|
shoulder len = .50 * diam
|
|
From these measurements I think it is clear that both the long cone and ogive were
|
|
intended to be 4:1 shapes, so I have adopted that in computing the nose cone lengths.
|
|
Shoulder diameters have been set at 0.1mm (0.004") smaller than the tube IDs.

<!-- MPC part numbering ("Stock No") for the 3 plastic nose cones 620PP, 625PA, and 630PS does
|
|
not match the convention for the balsa nose cones where the last character indicates the
|
|
shape. 625PA might be the A shape, but given that 620PP and 630PS do not end in A-B-C,
|
|
they are all in some doubt. My interpretation is that the P suffix means
|
|
"parabola" and indicates the round tip shape C, while the S suffix means "short" and
|
|
indicates shape B.
|
|
|
|
We have no data on the mass, so the plastic thickness is an educated estimate.

<!-- Transitions (called "Couplings" in MPC Catalog 2)
|
|
|
|
We have little hard data at all on the balsa and plastic transitions except the tube sizes they
|
|
connect. There are couplers in both plastic and balsa that couple the same size tubes as well as
|
|
differing sizes. We do know from the Microsonde-3 instructions that the plastic couplers had
|
|
separate end caps. Also from a photo of the Microsonde-3 with its T20-T25 coupler we can determine
|
|
that the exposed length is 25mm +/- 2mm.
|
|
|
|
Here are the assumptions made to model these parts:
|
|
Differing tube sizes
|
|
shoulder length = 0.5 * tube OD (roughly confirmed by catalog drawings)
|
|
exposed length = 25mm per 5mm of tube size change
|
|
shape is CONICAL (confirmed by catalog drawings)
|
|
Same size tubes
|
|
total length of bulkhead = 1.0 * tube size
