It looks good.

You're clear for
the probing run.

Stand by.

No, just go.

14
00:02:00,400 --> 00:02:01,150
Just go.

15
00:02:01,150 --> 00:02:04,310
Don't worry about that.

My name is Mike Frederick, and
I'm the principal investigator

19
00:02:28,460 --> 00:02:29,627
for the shock-sensing probe.

20

21
00:02:32,840 --> 00:02:35,990
The shock-sensing probe, it's
a five-hole conical probe

22
00:02:35,990 --> 00:02:37,830
that's used to measure
the near-field shock

23
00:02:37,830 --> 00:02:38,580
signature of X-59.

24
00:02:38,580 --> 00:02:42,410


25
00:02:42,410 --> 00:02:44,900
So right now, we're testing
out some new instrumentation

26
00:02:44,900 --> 00:02:47,060
that we have on the
shock-sensing probe

27
00:02:47,060 --> 00:02:49,270
to see if it's going to
be suitable for the probe

28
00:02:49,270 --> 00:02:51,020
in the near-field shock
signature of X-59.

29
00:02:51,020 --> 00:02:54,700


30
00:02:54,700 --> 00:02:56,740
Now, we're testing
it out on the F-15

31
00:02:56,740 --> 00:03:01,870
by flying it up at altitude
and probing another F-18, which

32
00:03:01,870 --> 00:03:03,190
is used as the target aircraft.

33
00:03:03,190 --> 00:03:06,770


34
00:03:06,770 --> 00:03:08,870
Typically, the F-15
starts in trail

35
00:03:08,870 --> 00:03:12,260
and outside the shock signature
of the target aircraft.

36
00:03:12,260 --> 00:03:15,680
And then we accelerate, so
the probe pierces the shocks.

37
00:03:15,680 --> 00:03:18,050
And essentially, we go all
the way through the shocks

38
00:03:18,050 --> 00:03:19,717
and we can see that
in the control room.

39
00:03:19,717 --> 00:03:22,040
And then once we've seen
that we've essentially

40
00:03:22,040 --> 00:03:24,110
pierced through the
bow shock of the F-18,

41
00:03:24,110 --> 00:03:27,080
we will ask the F-15 pilot
to decelerate and take

42
00:03:27,080 --> 00:03:28,477
another measurement.

43
00:03:28,477 --> 00:03:31,280


44
00:03:31,280 --> 00:03:33,860
First point you need to look is
the shocks near the aircraft.

45
00:03:33,860 --> 00:03:37,040
We need to understand the
magnitudes of that shock

46
00:03:37,040 --> 00:03:38,270
structure.

47
00:03:38,270 --> 00:03:42,603
Because right now, they use wind
tunnel tests, the recent wind

48
00:03:42,603 --> 00:03:45,020
tunnel test, and they've used
computational fluid dynamics

49
00:03:45,020 --> 00:03:47,690
to estimate what that shock
signature will look like.

50
00:03:47,690 --> 00:03:50,720


51
00:03:50,720 --> 00:03:54,470
When they go to fly phase two,
we will be in the control room

52
00:03:54,470 --> 00:03:56,930
monitoring the output from
the shock-sensing probe

53
00:03:56,930 --> 00:04:00,650
and then providing data
to the researchers that

54
00:04:00,650 --> 00:04:02,470
need that data.
