用不上 你速度再快都超越不了極超音速飛彈
而且這種設計只會破壞匿蹤 跟現在的主流設計根本背道而馳

The LN-3 Seagull

Drooping wing tips provide additional stabilization during water handling under severe conditions.
The design is made in compliance with FAR 23 Acrobatic Category thus making the LN-3 permitted for aerobatic flying.

>>高空高速
高空高速是二代噴氣式戰鬥機攔截戰略轟炸機的需求

導彈時代後戰略轟炸機淡出，都沒戰略轟炸機給你攔截了，三代機就開始追求低空亞音速性能了

四代機在機動上則要求超音速巡航和超音速下的機動能力

總之，現在戰鬥機並不需求高空高速

到也不是說不需要
而是無法有效率的快到能超越防守方攔截的手段

Hmm.

NASA Armstrong Fact Sheet: XB-70 Valkyrie

2014/03/01

To achieve Mach 3 performance, the B-70 was designed to "ride" its own shock wave, much as a surfer rides an ocean wave.
The resulting shape used a delta wing on a slab-sided fuselage that contained the six jet engines that powered the aircraft.
The outer wing panels were hinged.
During take off, landing, and subsonic flight, they remained in the horizontal position.
This feature increased the amount of lift produced, improving the lift-to-drag ratio.
Once the aircraft was supersonic, the wing panels would be hinged downward.
Changing the position of the wing panels reduced the drag caused by the wingtips interacted with the inlet shock wave.
The repositioned wingtips also reduced the area behind the airplane's center of gravity, which reduced trim drag.
The downturned outer panels also provided more vertical surface to improve directional stability at high Mach numbers.
Attached to the delta was a long, thin forward fuselage.
Behind the cockpit were two large canards, which acted as control surfaces.

這招好像是高超音速才有效
現代能在實戰拚得出來的高速 不會比超巡速度高太多
也就是2馬赫 至多也就瞬間2.2之類的(就算能再快也上不去 塗料會燒掉的)

這種程度的速度玩那招 不會有多大氣動上好處

Actuating wingtip devices

There has been research into actuating wingtip devices, including a filed patent application,[35] though no aircraft currently uses this feature as described.
The XB-70 Valkyrie's wingtips were capable of drooping downward in flight, to facilitate Mach 3 flight using waveriding.

https://en.wikipedia.org/wiki/North_American_XB-70_Valkyrie

The XB-70 used compression lift, which arose from a shock wave generated by the sharp leading edge of the central engine intake splitter plate below the wing.[73]
At Mach 3 cruising speed, the shock wave attached along the wing leading edge, preventing the high pressure behind the shock front from leaking up over the wing.[74]
The compression lift provided five percent of the total lift.[75]
The wing included inboard camber to more effectively use the higher pressure field behind the strong shock wave.
Unique among aircraft of its size, the outer portions of the wings were hinged, and could be pivoted downward by up to 65 degrees, acting almost as a type of variable-geometry wingtip device.
This increased the aircraft's directional stability at supersonic speeds, shifted the center of lift to a more favorable position at high speeds, and strengthened the compression lift effect.[76]
With the wingtips drooped downwards, the compression lift shock wave would be further trapped under the wings.

其實帝國海軍的D-7級輕戰巡很廢，D-10級重巡優良很多。
如無記錯，L-42級BOP也很好。
