Was genau passiert jetzt alles mit der B787 vom Erstflug bis zur ersten Auslieferung ?

Recommended Posts

Hast du schon mal überlegt wieviele Flugstunden und entsprechend dazu Auswertungsstunden anfallen? Das dauert nun mal seine Zeit. Ein Testprogramm umfasst locker 1000-1500 (wenn nicht sogar noch mehr) Flugstunden.

When the aircraft is completely assembled and instrumented, it typically conducts many hours of ground testing before its first/maiden flight. This ground testing will verify basic aircraft systems operations, measure engine performance, evaluate dynamic systems stability, and provide a first look at structural loads. Flight controls will also be checked out. Once all required ground tests are completed, the aircraft is ready for the first flight. First/maiden flight is a major milestone in any aircraft development program and is undertaken with the utmost caution.

 

There are several aspects to a flight test program: handling qualities, performance, aero-elastic/flutter stability, avionics/systems capabilities, weapons delivery, and structural loads. Handling qualities evaluates the aircraft's controllability and response to pilot inputs throughout the range of flight. Performance testing evaluates aircraft in relation to its projected abilities, such as speed, range, power available, drag, airflow characteristics, and so forth. Aero-elastic stability evaluates the dynamic response of the aircraft controls and structure to aerodynamic (i.e. air-induced) loads. Structural tests measure the stresses on the airframe, dynamic components, and controls to verify structural integrity in all flight regimes. Avionics/systems testing verifies all electronic systems (navigation, communications, radars, sensors, etc.) perform as designed. Weapons delivery looks at the pilot’s ability to acquire the target using on-board systems and accurately deliver the ordnance on target. Weapons delivery testing also evaluates the separation of the ordnance as it leaves the aircraft to ensure there are no safety issues. Other military unique tests are: air-to-air refueling, radar/infrared signature measurement, and aircraft carrier operations. Emergency situations are evaluated as a normal part of all flight test program. Examples are: engine failure during various phases of flight (takeoff, cruise, landing), systems failures, and controls degradation. The overall operations envelope (allowable gross weights, centers-of-gravity, altitude, max/min airspeeds, maneuvers, etc.) is established and verified during flight testing. Aircraft are always demonstrated to be safe beyond the limits allowed for normal operations in the Flight Manual.

 

Because the primary goal of a flight test program is to gather accurate engineering data, often on a design that is not fully proven, piloting a flight test aircraft requires a high degree of training and skill, so such programs are typically flown by a specially trained test pilot, and the data is gathered by a flight test engineer, and often visually displayed to the test pilot and/or flight test engineer using flight test instrumentation.

[edit] Analysis and Reporting

 

It includes the analysis of a flight for certification.It analyze the internal and outer part of the flight by checking its all minute parts. Reporting includes the analyzed data result.

Sogar doppelt soviel. Für die 787 sind insgesamt 3100 Flugstunden + 3100 Stunden am Boden angesetzt, was sich dann später auf sechs Flugzeuge verteilen wird.

Also jetzt weden 6 Testflugzeuge 1 Jahr lang alle möglichen tests durchführen.

 

Klick auf mein Thema "787 Flugtests" da findest du mehr zum aktuellen stand der tests. :D

 

 

(und nen link) und zu den neun monaten es wird hallt viel zeit gebraucht(es müssen ja alle tests ausgewetet werden...)

Backt man nun kleine Brötchen bei B? ""Es ist ein großer Schritt für uns, das Flugzeug in einen anderen Bundesstaat mitzunehmen", sagte Scott Fancher, Boeing-Vorstand und 787-Programmchef."

 

Sehe nicht, was an dem 2h Flug besonders ist. Was ist erst los, wenn man das Baby außer Landes bis nach Vancouver buchsiert? ;)

Schätze mal, in Seattle und Moses Lake hat man immer die eigene Infrastruktur zur Hand. Paar Techniker und Teile in eine Caravan setzen und fertig. Siehe der schnelle Triebwerkswechsel dort. Wenn die jetzt mit 150 Mann anrücken verrät es ja einen gewissen Aufwand.
