Question d'anglais et de vocabulaire

Recommended Posts

First a/c to be developed using an early form of "computational fluid dynamics" with an integrated "lifting body" type of theory rather than the typical (and obsolete) "blade element" theory.

First a/c designed to be data-link flyable from the ground.

First a/c designed with integrated navigation, weapons release, automatic search and track radar, datalink inputs, home-on-jamming, infrared detection, electronic countermeasures and counter-countermeasures operating through a DIGITAL brain.

First sophisticated bleed-bypass system for both intake AND engine/exhaust. Everybody uses that now.

First combination of the last two points with an "ejector" nozzle that used the bypass air to create thrust at the exhaust nozzle while also improving intake flow. The F-106 didn't even have a nozzle, just a pipe.

Use of a drooped leading edge and aerodynamic "twist" on the wing.

Use of engines at the rear to allow both a lighter structure and significant payload at the centre of gravity. Everybody copied that. *

Integration of ground-mapping radar and the radar altimeter plus flight control system to allow a serious strike/reconnaissance role. The first to propose an aircraft be equally adept at those roles while being THE air-superiority fighter at the same time. (Few have even tried to copy that, although the F-15E is an interesting exception.)

First oxygen-injection re-light system.

First engine to have only two main bearing assemblies on a two-shaft design.

First to use a variable stator on a two-shaft engine.

First use of a trans-sonic first compressor stage on a turbojet engine.

First "hot-streak" type of afterburner ignition.

c'est très interressant, mais j'ai du mal à comprendre la moitié de ce qui est écrit soit à cause de mon anglais soit à cause des termes techniques comme "premier étage de compresseur transsonique" . J'ai seulement cité les points que je n'avais pas compris.

Ce que j'aimerais c'est qu'un quelqu'un puisse m'éclaircir à ce sujet, merci d'avance.

* Je ne comprends ce qui a de si exeptionnelle là...
