Question

What could happen when an aircraft goes above it's speed limit by 110 knots?

Answer 1

I don't know of an aircraft that could do 110knots OVER the aircraft's limit without experiencing structural damage. whether the limit (Vne) is 2000kts or 10kts, doesn't matter. The energy from adding another 110 kts will very likely cause tears in the aircraft structure.

Only the angels can definitively tell you how long the airplane will stay in one piece if +110kts is maintained.

EDIT:

The primary enemies are INERTIA (particularly while craft is being accelerated in different directions by excessive thrust and by vibrations) and DRAG (by colliding with air with force that the frame cannot handle).

Answer 2

The main dangers are deformation of the wings and empenage and the biggest danger of all. Flutter.

Flutter is a kind of vibration that occurs when an aerofoil bends while producing lift. The load produces a bending movment. Once the load decreases, the original shape is restored, and the cycle repeats itself.

You will also propably overspeed the prop.

And why a 110 knots? Any flight operation above Vne is unmaped territory. You are the test pilot.

Answer 3

The air police will pull you over and give you a ticket.

Answer 4

It could start to vibrate a little.

Answer 5

Depending on the aircraft, this amount of airspeed can be enough stress to cause structual failure, where parts of the aircaft actually break/bend/crack or shear off the aircraft.

Aircrafts designs are extremely safe when operated within their operating limits. Its when these limits are exceeded, is when disasters tend to occur.

Aircraft designs have a max airspeed that that a/c can safely be operated at, known as Vne. But the design of the aircraft is designed to handle 150% above listed structual g's loads, as a margin of safety. This does not mean the operating the aircraft above Vne can be done safely.  Depending on the aircraft, 110knots, could exceed this safety margin, and the aircraft would come apart in smaller aircrafts.

In jets, this amount of airspeed depending on alitutude can cause many problems, one of the biggest is known as "Coffin Corner".  Its when an aircraft is high up, and any increase in airspeed will produce a shockwave, becasue the aircraft is hitting Critical Mach, and this makes the control surfaces not effective becasue of the lack of airflow due to the formation of a shockwave.  But slowing down in this sitution will not work either, because the aircraft will stall, hence the name..

Answer 6

Most aircraft cannot fly 110 knots above it's speed limit in level flight. It would probably have to be pointed at the ground.

If you try to slow it down, it may break up in flight. You may run out ot air before you could slow it down and it would hit the ground.

Answer 7

If the aircraft is a business jet and the 110knots brings its speed to greater than mach 1.0, then the aircraft windshield could potentially implode into the cockpit.
