00:08.229 --> 00:11.859
US . Solid rocket motor R and D design

00:11.869 --> 00:13.869
and manufacturing have markedly

00:13.878 --> 00:15.989
improved since their inception in the

00:15.989 --> 00:19.858
19 forties . However , this process has

00:19.868 --> 00:22.458
resisted change making the fielding of

00:22.468 --> 00:25.759
new Sr MS a time and resource intensive

00:25.768 --> 00:26.298
endeavor

00:31.920 --> 00:34.310
technology demonstration . Sr MS

00:34.319 --> 00:37.150
typically require 8 to 10 years to

00:37.159 --> 00:39.349
realize live fire testing and

00:39.360 --> 00:41.909
operational . Sr MS can require up to

00:41.919 --> 00:44.389
20 years for full rate production

00:46.020 --> 00:47.970
us supremacy and rocketry is

00:47.979 --> 00:50.349
diminishing and adversarial threats are

00:50.360 --> 00:54.319
coming of age . New methods are needed

00:54.330 --> 00:56.369
to accelerate tech transfer and to

00:56.380 --> 00:58.759
reduce barriers of entry to commercial

00:58.770 --> 01:02.569
firms . Production on demand seeks to

01:02.580 --> 01:05.010
advance four manufacturing technologies

01:05.019 --> 01:07.830
and develop an A FRL native rapid and

01:07.839 --> 01:10.830
flexible srmf typing capability .

01:12.559 --> 01:14.629
The interaction of micro fluidic

01:14.639 --> 01:16.660
reactor synthesis of precision

01:16.669 --> 01:19.300
ingredients , resonant acoustic mixing

01:19.309 --> 01:21.779
of solid rocket propellant additive ,

01:21.790 --> 01:23.610
manufacturing of solid rocket

01:23.620 --> 01:26.669
propellant and internal insulation and

01:26.699 --> 01:28.588
direct filament winding . We will

01:28.588 --> 01:31.050
afford a precisely controllable rapid

01:31.059 --> 01:33.849
prototyping capability for Sr MS .

01:36.739 --> 01:38.910
The production on demand program is a

01:38.919 --> 01:42.040
three phase program . In phase one .

01:42.050 --> 01:44.430
The development efforts in the four SRM

01:44.440 --> 01:46.639
technology areas are advanced in a

01:46.650 --> 01:48.309
compartmentalized fashion .

01:50.500 --> 01:52.790
Computational modeling and simulation

01:52.800 --> 01:54.720
tools will analyze the intended

01:54.730 --> 01:57.970
application of the srm glean the needed

01:57.980 --> 02:00.580
specifications and select a design

02:00.589 --> 02:03.629
based on those results . Once a

02:03.639 --> 02:05.980
demonstration threshold is achieved for

02:05.989 --> 02:08.649
resonant acoustic mixing , 3d printing

02:08.710 --> 02:11.360
and direct filament winding integration

02:11.369 --> 02:13.559
of the process elements will begin

02:14.779 --> 02:16.509
successful integration of the

02:16.520 --> 02:19.809
production on demand or pod process

02:19.820 --> 02:22.059
elements will utilize machine learning

02:22.070 --> 02:23.800
principles require network

02:23.809 --> 02:26.460
communication of equipment and minimize

02:26.470 --> 02:28.850
the need for human labor . The process

02:28.860 --> 02:31.360
elements work together by first

02:31.369 --> 02:33.500
selecting a propellant formulation

02:34.429 --> 02:36.779
station . A then remotely doses the

02:36.789 --> 02:39.020
solid and liquid ingredients for a £2

02:39.029 --> 02:40.862
batch of solid propellant into a

02:40.862 --> 02:43.550
container . Safety concerns are taken

02:43.559 --> 02:45.960
into full account during dosing . Once

02:45.970 --> 02:48.137
ingredients are dosed , the containers

02:48.137 --> 02:50.149
are sealed and passed to the RA M

02:50.160 --> 02:51.529
platform for mixing

02:55.979 --> 02:58.289
additive manufacturing is utilized to

02:58.300 --> 03:00.522
not only print the propellant grain but

03:00.522 --> 03:02.467
also to print the motor's nozzle .

03:07.750 --> 03:09.729
The 3D printing Cobos work in

03:09.740 --> 03:12.220
conjunction with one laying down layers

03:12.229 --> 03:14.118
of material and the other using a

03:14.118 --> 03:16.410
curing device attached to its wrist .

03:16.949 --> 03:18.949
After each layer is produced an

03:18.960 --> 03:21.729
additional Cobo arm scans the surface

03:21.740 --> 03:24.100
looking for flaws that other Cobos can

03:24.110 --> 03:27.429
repair . After printing the propellant

03:27.440 --> 03:29.440
grains are transferred to a storage

03:29.440 --> 03:31.679
rack and then onto a filament winding

03:31.690 --> 03:34.360
shaft . In a rare case of human

03:34.369 --> 03:36.591
interaction , the vertical film winding

03:36.591 --> 03:39.130
machine , the operator and a cobo work

03:39.139 --> 03:41.361
collaboratively to install the internal

03:41.361 --> 03:43.528
insulation in the composite structural

03:43.528 --> 03:44.020
case ,

03:48.460 --> 03:50.839
the completed srm are removed from

03:50.850 --> 03:53.110
final station and is ready for use

03:57.369 --> 03:59.509
during the automated manufacturing of

03:59.520 --> 04:02.250
the Sr Ma digital twin is created

04:02.259 --> 04:04.520
through the inspection process . The

04:04.529 --> 04:06.679
digital model can be used to predict

04:06.690 --> 04:08.634
performance and further refine the

04:08.634 --> 04:11.350
manufacturing process in the final

04:11.360 --> 04:13.471
phase of the project , redesigned and

04:13.471 --> 04:16.190
more advanced AM Ram five rocket motors

04:16.200 --> 04:18.630
will be manufactured by the pilot plant .

04:20.609 --> 04:22.790
Ultimately using those grains . The

04:22.799 --> 04:25.179
full AM ram five rocket motor will be

04:25.190 --> 04:27.320
manufactured by the pilot plant and

04:27.329 --> 04:29.799
static fire tested elsewhere on site .

04:35.899 --> 04:37.788
The pursuit of solid rocket motor

04:37.788 --> 04:39.880
production on demand will mobilize ,

04:39.890 --> 04:42.750
fortify and stabilize the US rocket

04:42.760 --> 04:46.709
motor supply base . It

04:46.720 --> 04:48.387
will provide rapid design and

04:48.387 --> 04:50.640
fabrication of customized rockets for

04:50.649 --> 04:52.730
any end use requiring specific

04:52.739 --> 04:55.459
performance . This system will

04:55.470 --> 04:57.690
dramatically shorten time to design

04:57.700 --> 05:00.489
prototype and acquire new motor designs

05:00.500 --> 05:02.722
and improve the safety of manufacturing

05:02.722 --> 05:03.859
for those designs .
