[PTA Slowchat] Rockwell / MBB X-31 @ 975 MPH

De OP
The collaborative U.S.-German Rockwell-MBB X-31 Enhanced Fighter Maneuverability program was designed to test fighter thrust vectoring technology. Thrust vectoring allows the X-31 to fly in a direction other than where the nose is pointing, resulting in significantly more manuverability than most conventional fighters. An advanced flight control system provides controlled flight at high angles of attack where conventional aircraft would stall.

Two X-31s were built, and over 500 test flights were carried out between 1990 and 1995. The X-31 featured fixed strakes along the aft fuselage, as well as a pair of movable computer-controlled canards to increase stability and manuverability. There are no horizontal tail surfaces, only the vertical fin. Pitch and yaw are controlled by the three paddles directing the exhaust (thrust vectoring). Eventually, even the vertical fin on one of the two X-31s was also removed as it had no control surfaces. Yaw and pitch were both controlled by the thrust-vectoring nozzle, therefore the vertical fin was deemed superfluous.


During flight testing, the X-31 aircraft established several milestones. On November 6, 1992, the X-31 achieved controlled flight at a 70-degree angle of attack. On April 29, 1993, the second X-31 successfully executed a rapid minimum-radius, 180-degree turn using a post-stall maneuver, flying well beyond the aerodynamic limits of any conventional aircraft. This revolutionary maneuver has been called the "Herbst Maneuver" after Wolfgang Herbst, a German proponent of using post-stall flight in air-to-air combat.

In the mid nineties the program began to revitalize and a $53 million VECTOR program was initiated capitalizing on this previous investment. VECTOR is a joint venture that includes the US Navy, Germany’s defense procurement agency BWB, Boeing Phantom Works and European Aeronautic, Defence and Space Company in Ottobrunn, Germany. As the site for the flight testing, the Naval Air Station Patuxent River in Maryland was chosen. From 2002 to 2003 the X-31 flew extremely short takeoff and landing approaches first on a virtual runway at 5,000 feet in the sky, to ensure that the Inertial Navigation System/Global Positioning System accurately guides the aircraft with the centimeter accuracy required for on the ground landings. The program then culminated in the first ever autonomous landing of a manned aircraft with high angle of attack (24 degree) and short landing. The technologies involved a differential GPS System based on pseudolite technology from Integrinautics, California, and a miniaturized flash air data system from Nordmicro, Germany.

Het gaat niet alleen om de race zelf, maar ook om het programma eromheen. Dat is, afgezien van Wietske, dermate tenenkrommend dat ik er eigenlijk niet meer naar kijk.

Het programma er om heen is idd knap waardeloos, maar ik vond die Ruud dinges bij RTL vroegâh ook geen haar beter.

De oude, te wijze man, tya...
Toegegeven, dat was ook niet alles... maar ik had nog wel de neiging om de rest van het voorprogramma te bekijken omdat daar genoeg andere leuke dingen in voorkwamen.

Ik vind het overigens ook vernederend dat die coureurs niet voluit durven te gaan in de simulator omdat ze dan wel eens van de baan af kunnen vliegen Je ziet ze nu in een fiat panda rondcruisen en wat zachtzinnige verhaaltjes ophangen bij de bochten.

ze gaan niet voluit omdat ze dan niet de layout van het circuit kunnen vertellen in de 80 seconden
