It is a twin-seat, twin-engined aircraft with a variable geometry swing-wing that is capable supersonic flight at all levels.
这是一个双座位，可变几何摆动翼是能在各级超音速飞行的双引擎飞机。
The idea is to oscillate the turbocharger’s variable geometry and synchronise it with the engine exhaust to get better energy recovery from the pulsating exhaust flow.
这个创意是通过调节涡流增压器的结构来使它与引擎尾气排放同步，从而达到更好的能量回收效果。
Somewhat like the European Union, the alliances have “variable geometry”: members do not have to join all initiatives, and non-members sometimes take part in selected activities.
而在欧盟，这些联盟则有“可变机翼”的规则：联盟成员不必参加所有的活动，而非联盟成员有时候可以参加特定的活动。

Variable geometry will grow rather than recede with the passage of time.
