It all depends on the area of impact (on the wing) the angle of impact, and which portion of the sUAS strikes the aircraft.
I'll be brutally honest here.... how could anyone just simply dismiss the video of a "Phantom Like" aircraft penetrating the wing skin like that? Yes they simulated a direct full-on strike and probably on a less rigid portion of the wing but why would you NOT test Worse Case Scenario?
The "Evidence" that the YT showed of the Canadian aircraft is bull... they don't know which drone hit it, what angle it hit it, or which portion of the drone hit it. It could have simply been the soft plastic undercarriage that "Scuffed" the aircraft wing.....
What you have to remember in these cases, is that some labs may not be playing fair, while other may. For example, if the drone can only reach a max. speed of 42MPH and the aircraft in question can only reach a max. straight and level speed of, for example 150MPH, then the testing should be done so that the wing is sped up to a combined speed of 192MPH when it impacts the hanging drone, or the drone is propelled at this same speed when it is shot at the stationary wing of the aircraft. If the lab decided to shoot the drone at the wing at a speed of 250MPH then of course the wing would sustain more damage. However, that would not be a real word happening and that resultant data would be extremely misleading, as well as incorrect.
Of course there are many different aircraft that fly through the sky and these have greatly differing speeds at cruise and resulting damage at higher speeds is always going to be more severe. With that said, at cruse speed those aircraft are always at higher altitudes, and the average drone flier is never going to be flying at those altitudes, which means that a drone strike is as likely as being in a tornado while living in northern Canada. We can not say that no one is going to fly a drone at high altitude but we can assume that if we are considerate about the rules, a strike between the two aircraft will likely not happen. Yes anything can happen but that is outside of all our control.
Many years ago when the British government sold the British invented Harrier jet to the US military, they stated that the cockpit canopy could sustain impact from a number of sized birds with no damage. Not wanting to accept that data, the US wanted to carry out their own testing, and sure enough, they were able to shatter canopy glass of the Harrier. Just reading this would have many believe that the British testing was flawed or biased.
When the US testing was looked into in more detail, the British discovered that the US were propelling frozen birds at the canopy, which was not a real world testing procedure. Of course a frozen chunk of flesh is going to impart more damage on the canopy than a soft natural body of a bird. Therefore, when reading testing data, it is best to be able to source all the information possible regarding those test, to be sure they were done correctly and fairly.
The other thing to consider, when assessing what damage a drone might do to an aircraft, is the type of aircraft that might come into contact with the drone. Everyone seems to be thinking of a Jet airliner or a Cessna high wing aircraft, which are both metal covered aircraft. They also seem to assume that a drone would hit the leading edge of a wing. I suspect that most here have never taken into consideration that there are many much lighter weight aircraft also flying through the sky.
Aircraft such as fabric covered Piper Cubs and other type of fabric covered aircraft, some internal metal structures and some with wooed built wings. Then there are props to consider, the majority of props are metal but there are a number of aircraft that fly with wooden props which would sustain more damage than a metal prop in such an impact. But even a bolt left on the ground that a prop might suck up can cause a slight fracture that does nothing at that point, but over time that crack can propagate to a point that part of the blade could shear off in flight.
When an aircraft loses a piece of propeller in flight it is not a good day. There can be a minor shake to a severe shake, due to imbalance of that prop. A severe imbalance can create such a shake, that if not immediately attended to, could possible shake the engine off its mountings. If an engine was to fall off in flight, those aboard had better have jam in their pockets, because they will be toast! An aircraft's CG is finely balanced for flight, from passenger placement to baggage placement, and the loss of an engine in a small single engine aircraft would be catastrophic, due to the aircraft's CG being so far out, it is not recoverable.
There is another thing to think about in drone strikes and that is, not all strikes may be on the leading edge of a wing, it may be a tail structure which is not as hefty as a wing and may sustain more damage than a wing strike. Again this could cause an aircraft to crash and kill all on board. Now, all this is highly unlikely to happen as long as we don't fly drones in areas that are close to GA aircraft and that pilots keep themselves high enough to avoid a strike with a slightly higher flying drone, than the new laws allow, just to keep that buffer in altitude a safer buffer. But when considering the damage a drone can do to an aircraft, there are all sorts of man carrying aircraft up there, from delicate ultralights to high speed jet airliners and all at different speeds and altitudes, so be mindful of that when flying. I'm not the drone police but I am both kinds of pilot and we should both consider the other and their safety when flying.
