00:00.371 --> 00:02.954
(upbeat music)

00:04.800 --> 00:05.839
- My kinda focus has been really,

00:05.839 --> 00:08.570
kinda in more of a
design for space systems,

00:08.570 --> 00:09.780
and specifically looking at

00:09.780 --> 00:12.100
the structural bus of a satellite.

00:12.100 --> 00:14.670
The big reason, the push and motivation

00:14.670 --> 00:16.530
for research is kinda
that rapid innovation,

00:16.530 --> 00:19.670
rapid deployment, so ideally,
or if there's new satellite,

00:19.670 --> 00:21.260
we have some new payload
we wanna get up there,

00:21.260 --> 00:23.640
and we need it up there
as soon as possible,

00:23.640 --> 00:26.500
this gives the ability to
quickly design and deploy

00:26.500 --> 00:28.940
a new structural bus that
could carry that payload.

00:28.940 --> 00:32.880
Using 3D printing, that
gives you this really complex

00:32.880 --> 00:34.530
design space that you can use.

00:34.530 --> 00:36.030
You kinda leverage that to create

00:36.030 --> 00:40.600
a very lightweight, stiff,
structure, in a very quick time.

00:40.600 --> 00:43.600
You can design something in a CAD program

00:43.600 --> 00:47.620
and then, the next day load
that up into a 3D printer

00:47.620 --> 00:49.800
and then print it, and then
have something in your hand

00:49.800 --> 00:51.100
within, a couple days.

00:51.100 --> 00:52.720
The big thing with satellite chassis

00:52.720 --> 00:55.280
or structural buses, is vibrations,

00:55.280 --> 00:57.370
and so a lot of the focus
on building a structure

00:57.370 --> 00:58.590
is making it lightweight and stiff

00:58.590 --> 01:01.190
so that it can have a
higher resonance frequency

01:01.190 --> 01:03.500
so that when it launches,
it's not resonating

01:03.500 --> 01:06.640
at the same frequency as
the actual launch vehicle's

01:06.640 --> 01:08.670
guidance navigation system,
'cause then you're gonna

01:08.670 --> 01:11.130
throw everything off and you
don't want that failed launch.

01:11.130 --> 01:12.790
So, one of the big things that we did,

01:12.790 --> 01:15.290
is after we built our
parts and built our chassis

01:15.290 --> 01:18.970
and we would take them and
put them on the shaker table

01:18.970 --> 01:21.320
and we'll put it through
a vibration profile.

01:21.320 --> 01:22.980
This research is important
because it allows us

01:22.980 --> 01:24.460
to push the boundary of what we can do

01:24.460 --> 01:25.990
with traditional manufacturing

01:25.990 --> 01:27.740
and allows the ability to quickly iterate

01:27.740 --> 01:28.770
and develop a process

01:28.770 --> 01:31.110
and determine the failure
points earlier on,

01:31.110 --> 01:34.600
so that we can then produce
something better, sooner,

01:34.600 --> 01:36.360
than we could if we were following

01:36.360 --> 01:38.253
a traditional means of manufacturing.
