Variable-pitch fan blades are generally required for thrust reversal in such ultrahigh-bypass fans, while in medium- and high-bypass engines the thrust reversing is usually accomplished by introducing blocker doors into the bypass stream.
Some work had been done on an engine part, a thrust reverser, shortly before takeoff.
In rich bureaucratese, we learn that failure in the thrust reverser "could result in large pieces of the T/R or adjacent components departing the airplane".
After the crash, the US federal aviation administration ordered airlines to install an extra thrust reverser locking system on a wide range of Boeing aircraft, although such orders are not binding on carriers based outside the United States.
On Oct. 31, 1996, in another Fokker 100, also flown by TAM, a thrust reverser deployed on takeoff, and all 95 people on board died, along with four more on the ground.
Passengers might not be thrilled to learn that the F.A.A has received 14 reports of "events" related to thermal damage in the inner wall of the thrust reverser (T/R) on the engines.
The complaint, filed yesterday by the estates of three German travelers who died in the crash, contends that two events thought to have caused the crash -- a 16-inch metal strip falling off a Continental DC-10's thrust reverser, and the blowout of a Concorde tire that hit the strip on the runway -- were such common occurrences that the crash could and should have been prevented.
With its function of decreasing the ground roll distance, thrust reverser (T/R) may cause safety problems in case of its inadequate integration with the aircraft.
This paper concerns the design of adaptive controller for fault-tolerant control (FTC) of aircraft nacelle and especially the thrust reverser subjected to functional defects.
In fact, this article addresses this problem by the use of Principal Components Analysis (PCA) for faults detection in electrical machine used to control the doors of the aircraft thrust reverser.
