We've all heard that flying is the safest way to travel, and statistically it is. 00:00:00
Even as our world's airspace becomes more crowded, flying today is actually becoming 00:00:11
safer. 00:00:15
But unfortunately, fatal aircraft accidents can still occur. 00:00:16
That's why researchers in the Aviation Safety Program are working on revolutionary technologies 00:00:19
that may make fatal aircraft accidents a thing of the past. 00:00:24
The Single Aircraft Accident Prevention Project, or SAP, is part of the Aviation Safety Program 00:00:28
that is developing new technologies that may help pilots recover and safely land an aircraft 00:00:34
from a potentially fatal event. 00:00:39
I spoke with John Foster in the Vehicle Dynamics Branch at NASA Langley to find out more about 00:00:41
SAP. 00:00:46
The SAP project is developing systems that will anticipate failures on the airplane before 00:00:47
they occur and help the pilot recover the airplane if an out-of-control event should 00:00:53
occur. 00:00:58
What's an example of an out-of-control flight situation? 00:00:59
Well, there are a number of factors that can contribute to an airplane loss-of-control 00:01:02
accident. 00:01:07
These factors can be both internal or external to the airplane. 00:01:09
Some external factors may include severe weather or just poor visibility. 00:01:13
Some internal factors, though, could include some failure in the control system as well 00:01:18
as a structural failure or just an inappropriate crew input. 00:01:23
In many of these situations, catastrophic failures cause the pilots to lose control 00:01:27
of the airplane, resulting in a fatal accident. 00:01:31
Researchers in the SAP project are working on new technologies, which they hope will 00:01:35
prevent these types of accidents from ever occurring again. 00:01:38
They're developing a series of revolutionary systems that will not only detect and predict 00:01:42
system or component failures before they become severe, but are also developing automatic 00:01:45
control recovery systems, which will actually help pilots recover an airplane from an upset 00:01:50
situation. 00:01:55
Okay, so how do these systems help a pilot out? 00:01:56
I mean, how do they work? 00:01:59
Well, the vehicle health management system is being developed, which will continuously 00:02:00
monitor the airplane's health and compare that to the math model for a healthy airplane. 00:02:05
In case a disturbing trend or an anomaly occurs, it can send that information to the 00:02:12
ground crews, and they can take the appropriate maintenance action to fix the part after the 00:02:17
airplane lands. 00:02:22
Wow, kind of like an onboard doctor. 00:02:23
Exactly. 00:02:25
That's why it's called health monitoring. 00:02:26
Another system being developed as part of the SAP project is the control recovery system. 00:02:27
This system is being designed to help the pilot in case the airplane gets into a loss 00:02:33
of control situation. 00:02:37
That system will carry a math model of a normal maneuvering airplane on board. 00:02:39
And if the system detects that the airplane is about to enter a loss of control situation, 00:02:45
it can alert the pilot and help him to recover the airplane, or it can automatically recover 00:02:50
the airplane for the pilot. 00:02:55
These systems will not only be able to help a pilot regain control of an aircraft quickly, 00:02:57
but will also be able to help land an aircraft that has suffered catastrophic damage. 00:03:01
With these new systems on board commercial planes, pilots will be able to maintain safe 00:03:05
flight even under the most adverse flight conditions, potentially making fatal crashes 00:03:10
a thing of the past. 00:03:15
Okay, so the systems you've mentioned are obviously computer systems, but we're standing 00:03:16
here in a wind tunnel. 00:03:20
How does wind tunnel testing help? 00:03:21
Well, wind tunnels are used to develop pilot training simulators. 00:03:23
We can take the data out of the wind tunnel for extreme flight conditions and put that 00:03:27
in the simulator and allow the pilot to experience an out-of-control event and conduct training 00:03:32
to learn how to recover from such a situation. 00:03:37
Our goal is to provide the most realistic training possible for the pilots in case they 00:03:40
would enter a loss-of-control situation. 00:03:46
John, how will these systems be tested before being implemented on an airplane? 00:03:48
Well, there are several methods that we can use to test the systems before they are actually 00:03:52
implemented in the airplane. 00:03:57
One is to use a subscale, dynamically scaled flying model of the airplane. 00:04:00
In that model, which is remotely controlled, we can install the actual systems in onboard 00:04:06
computers and then fly the model through various out-of-control flight conditions and then 00:04:12
see how the system works to recover the airplane. 00:04:18
What are your hopes for the future of this project? 00:04:20
I mean, what are the future goals of SAP? 00:04:23
Well, flying is already a very safe form of transportation, but accidents still occur. 00:04:25
And our goal in this research is to develop systems that will specifically help reduce 00:04:31
those kind of accidents and save lives. 00:04:36
