Can any aircraft beat this car's 0-400-0 km/h record of 28"?
In 2024, the KOENIGSEGG Jesko Absolut set a new world record for 0-400-0 km/h. That's starting from 0 km/h, accelerating to 400 km/h and then decelerating to 0 km/h again.
Without such easy rolling ...

Does a longer wing produce same lift as a wider wing with the same total area?
Considering the image below, as shown, both wings have the same total area but with different
different measures.
Do they produce the same lift, or which wing produces more lift and which one makes ...

Can someone explain the damage distribution on this aircraft that flew through a hailstorm?
An A320 flew into a hailstorm 20mins from landing. I’m intrigued by the damage distribution. Seems like everywhere else wasn't touched at all. Why?

In a straight and level flight if thrust is equal to drag how is aircraft moving forward?
If two forces are equal and acting in opposite direction should not the object remain stationary.
Is there an excess thrust which actually pushes the aircraft forward ?

induced drag at supersonic speed [duplicate]
for a delta wing with supersonic leading edge at small angle of attack there is no stagnation point on leading edge so There is no connection between the top and bottom of the wing. Therefore, the air ...

In a hot air balloon what proportion of the lift comes from the heated air compared to that from the combustion products?
A hot air balloon is heated with propane or similar hydrocarbon. One of the products of combustion is H2O with molar mass 18 so it is substantially less dense than air (78% nitrogen, molar mass 28 and ...

Does partial flow separation due to toggle input affect the physics of paraglider/ canopy controls?
A skydiving canopy designer said the following:
Airflow is separated even before stall on a big portion of the canopy.... It's specific to [the] way toggle[s] distort the trailing edge.
Is this true,...

Does ground effect affect a paraglider/ canopy?
I've heard that ground effect is only significant if the wing is closer to the ground than its span, and I've never seen a canopy/ paraglider that would qualify for that.
Is that true or would there ...

Is the thrust/lift trade-off for powered lift linear?
On the wikipedia page Powered lift there is this graph of thrust vs lift: (public domain)
This graph shows a roughly constant (not exactly constant but that's not the point) sum of thrust and lift. ...
