Weiss jemand, was hier passiert ist?

[Staubsauger]

Hallo zusammen

 

Ich bin wieder einmal die Pannenliste auf http://www.micom.net/oops/ durchgegangen und bin auf dieses Video gestossen: http://www.micom.net/oops/F14aExplosion.wmv

 

Weiss jemand, was hier das Problem war, es scheint ja nicht, dass die F-14 Probleme hatte.

Hallo,

 

Weiss jemand, was hier das Problem war, es scheint ja nicht, dass die F-14 Probleme hatte.

wissen ist so eine Sache. Ich habe das Video schon auf einer anderen Website gesehen und dort stand geschrieben, das der Pilot für das Manöver etwas zu schnell war. Die Maschine sei beim "starken Hochziehen" nach diesem Vorbeiflug regelrecht zerbrochen...

 

spekulativen Gruss,

Habe das hier "gefunden":

1) I am a Navy Air Traffic Controller.

2) I was stationed aboard the USS Abraham Lincoln (CVN 72) From 1994-1999.

3) I was on Marshal Control in the Carrier Air Traffic Control Center (CATCC) when this accident happened.

 

I’m not certain how many specifics I can get into. I do not think I can get into where we were exactly or where we were going. However, the accident report has been declassified and as such I can relay a few pertinent facts about what happened.

 

I was tracking the Aircraft and he was traveling at a high rate of speed. He never requested to do a flyby on the John Paul Jones and since he was inside my airspace (out to 60 nautical miles) he should have made a request to do so. Fact is he never was in communications with me at all.

 

Naval investigators concluded the loss of the airplane was due to "pilot error" because Bates failed to take the required action to prevent his plane from going into an uncontrollable spin after an engine stall.

 

The F-14 he was flying was an F-14A and the engines on that series were prone to compressor stalls when making high angle of attack maneuvers, at high speeds, in dense atmosphere (read: Low altitude). At the time of this accident they were transitioning to the F-14B with engines that were 30% more powerful.

 

Because of the great distance between F-14 engines, asymmetrical thrust becomes a real problem should one engine fail.

 

Going outside of the official mishap investigation; it would appear to me that just prior to the explosion, LCDR (Lieutenant Commander) Bates place his aircraft in a very hard turn. If you look at the video, you will notice the aircraft flying at a 90-degree wing down attitude just prior to the explosion.

 

As I stated earlier; Naval investigators concluded the loss of the airplane was due to "pilot error".

 

Some of you may recall there was an F-14 accident in January of 1996. In this accident the pilot requested an "Unrestricted climb" and his departure took him vertical. He was observed to pass into an overcast layer of clouds at nearly a 90-degree angle of attack. Shortly after he was seen going into the clouds, his aircraft reversed direction and impacted a house. The pilot, RIO (Radar Intercept Officer) and three people on the ground were killed.

 

The findings on this accident were also found to be "pilot error".

 

Can you guess who the pilot of the later flight was? If you guessed LCDR John Stacy Bates you would be correct.

 

In a period of 16 months, there were 4 losses of F14's in LCDR Bates' squadron, VF-213 the Fighting Black Lions. Two of which were attributed to him.

Well it seems some many answers, but you are all wrong.. Now take it from a old Navy Captain whos been there, done that.. Here is the true story as it happened. The F-14A TomCat, BuNos 161146 was TARPS-capable with VF-123 off the aircraft carrier U.S.S. Abraham Lincoln There was no supersonic speed or sound barrier broken here. USS John Paul Jones (DDG 53) rescued two air crew after they ejected from a Navy F-14A on Sept. 20, while conducting routine operations in the Pacific Ocean, 800 miles west of Guam. The aircraft was from Fighter Squadron 213 (VF-213), based at Naval Air Station Miramar, Calif., and attached to Carrier Air Wing 11. USS John Paul Jones is a part of the Abraham Lincoln Battle Group. The crew of John Paul Jones had gathered topside to watch an F-14A Tomcat fly-over and maneuver as part of a battle group exercise. The crew was watching as the F-14A approached from the stern on the starboard side when suddenly, as the aircraft p****ed amidships, a ball of fire erupted from the tail section. Crew members saw a violent explosion and the jet disintegrated in mid- air. It took the crew only seconds to transition from spectator to search and rescue. Lookouts on the bridge wings spotted two parachutes drifting towards the sea amongst the debris. Rescue coordination was quickly established between the officer of the deck, the combat information center (CIC) and the rescue boat detail. The general announcing system directed the crew to man the Rigid Hull Inflatable Boats (RHIB). Within minutes the RHIB was lowered into the water and sped toward the parachutes location to ****ist the two downed crew members. The RHIB was directed from the bridge wing to the smoke marking the downed air crew. The rescue RHIB came upon the aircrafts radar intercept operator (RIO) who appeared in good shape. Indicating he was OK, he pointed to his pilot, floating some 50 yards away. Arriving at the pilot, the rescue swimmer jumped into the water while the corpsman verified that he was in good medical condition. Recovering both the pilot and the rescue swimmer, the RHIB repositioned to recover the RIO. The swimmer reentered the water to conduct a quick medical check and found the RIOs legs fouled by a line. Cutting the line and raft seat away from his legs, the swimmer realized the RIO had more serious burns than the pilot and the RHIB crew carefully brought the RIO on board. The RHIB rescue crew safely recovered the air crew in only eight minutes. CIC provided the bridge with accurate course recommendations while updating the battle group commander with the air crews position and medical status. The air crew was taken to the medical dispensary for further treatment while awaiting the arrival of the carrier-based helicopter to return them to USS Abraham Lincoln. As they were leaving, the air crew expressed their gratitude for their rapid ****istance and rescue to the ships company who had gathered on the mess decks. USS John Paul Jones is ****igned to the Abraham Lincoln Battle Group, under the operational control of Commander Carrier Group 3, RADM Robert M. Nutwel, homeported in Alamdea, Calif. John Paul Jones is the first Arleigh Burke cl**** destroyer to deploy to the western Pacific and is returning to its home port of San Diego after a six month deployment to the western Pacific and Arabian Gulf, where it participated in Operations Desert Storm, Southern Watch and Vigilant Sentinel. USS John Paul Jones is commanded by CAPT Peter B. Opsal, of Richfield, Minn. The ship is 505 feet long, 67 feet wide, displaces approximately 8,600 tons and carries a crew of 353. John Paul Jones is the third of the new Arleigh Burke cl**** of destroyers. The ship was commissioned on Dec. 18, 1993, and is designed to conduct a variety of missions including launching Tomahawk land attack missiles, anti-air defense and anti- surface/subsurface warfare duties. The cause of the accident is under investigation. -vy Captain whos been there..

Ohne Garantie auf Echtheit :D :D

Danke euch beiden.

 

Aber das ein Compressor stall eine solche Explosion auslösen kann leuchtet mir nicht ein.

[Johannes Müller]

So wie ich es verstanden habe (was nicht viel heissen will :D), war nicht der compressor stall das problem sondern der "uncontrollable spin", welcher durch den asymetrischen Schub (ein Motor an, der andere aus) verursacht wurde. Ich staune eigentlich nur, dass sich Pilot und Copilot rechtzeitig retten konnten, das musste ja innerhalb von Bruchteilen von Sekunden passiert sein (bzw man sieht wenig / nichts davon auf dem Film, vielleicht war es auch nicht so schnell?)

[skydiver]

auch von micom.com, aus der D-FALK hab ich vor 10 Jahren meinen Tandemsprung gemacht..

so sieht man sich wieder:D

[blipper]

sind ja alles interessante Sachen, aber wenn man bei grossen Geschwindigkeiten hochzieht, sollte nicht nur einfach der Kurvenradius grösser werden, und das war's dann? Die F14 ist ja soviel ich weiss auf ca. 7.5g begrenzt. Dass es so eine Maschine einfach so zerreist, bezweifle ich mal. Auch das mit dem Unsymmetrischen Schub ist nicht ganz einleuchtend. Klar, bei asymmetrischem Schub gibt es eine Gierbewegung, aber auch hier, ob das ausreicht, die Maschine in zwei Stücke zu reissen?

 

Ich stelle mal die Vermutung in den Raum, das war eine iranische F-14 über dem persischen Golf, die abgeschossen wurde :p

Tja wohl alles Spekulation. Die Geschichten tönen eigentlich plausibel. Wieso sollte sich jemand sowas ausdenken?

Kann mir durchaus vorstellen, dass ein Triebwerksausfall und eventuell folgende starke Ruderkorrekturen bei so hohen Geschwindigkeiten die Zelle überlasten könnten. Ach ja: Hab ich da noch ne Überschalldruckwelle gesehen??

 

@Alex:

Dann wär sie nie so nah ran gekommen - oder wenn doch, wäre das "Beweisvideo" sicher top secret :p
