A typical bow has a draw weight of around 60 lbf (high), or 266 N.
Most modern arrows are 75 to 96 10^-2 m (cm) long, taking 85 10^-2 m as an average.
Work-energy theorem gives the kinetic energy as E_k = 1/2 * 266 N * 0.85 m = 113.05 J.
Kinetic energy is given by 1/2 m v^2. Accordingly, the velocity will vary by mass
v = sqrt( ( 113.05 * 2. ) / m )
For a 0.1 kg (100 g) total arrow mass, including the explosive payload, the discharge speed is about 47 m/s, which is impactfully low. One can quickly see the constraints of this method. The helicopter must be lightly-armored, flying very low and slow for this to have any non-negligible probability of success.
The ideal setup would likely be a guided arrow fired from a mechanical crossbow, mounted on a stabilized, gunmaker platform, with a shaped charge to target the helicopter’s tail.
I should add that a pedal-powered ballista on a platform similar to an anti-aircraft gun might be ideal for this application. The design would likely consist of a central rail supporting arms made of a high-elasticity material, such as spring steel or an aluminum-vanadium-titanium alloy. A good cyclist can put out around 300 W for a reasonable period. You could launch an object with roughly the form factor and mass of a guided missile at a very high speed.
AI is not very good then, it does not encompass the sine of the arrow or the material, a cross bow is a terrible choice as well, this is because the amount of energy imparted on a shorter draw. far better off with a compound and hollow correct spine arrows. The whole idea is king dumb though. Crossbows if they have a place are for psychological intimidation of the likes of mobiks to make them afraid of the night and only in rare circumstances
Not easily because you're firing upwards at least 40m, and more likely you're going to be firing a deflection shot 500m or further away at a target that is flying 200km/h or faster.
>Could you hypothetically destroy a low flying helicopter with bow and arrow with explosive tip?
Mythbusters did this. But you definitely can make a better explosive arrow than they did by filling the whole shaft with RDX . Now 16-20 grames of RGX is not insignificant its enough to kill someone akin to a shotgun blast but on a helicopter? You would have to be fricking lucky, for a start the rotor down draft would nearly certainly drive the arrow in flight straight down into the ground or off course. A better solution might be to lob an arrow with a kevlar line attached to a steel cable over the rotor and hope the rotor or tail rotor pulls the kevlar line in and then the steel cable and fricks the rotor but you would have to be within 50-80 meters. You'd have to be in a spiderhole at a landing or extraction site basically ready to go
Yeah man I did it in farcry 5 like a hundred times.
I'm gonna say it.
4 was better than 5.
Tame a pterodactyl to ride and shoot it from above (try to target rotors or windshield)
Thanks for the demoralization Cia

>bow and arrow with explosive tip
Is there even such a thing?
One could make it
It's not rocket science
arrow science
Yes, they are most commonly used to hunt predatorial extraterrestrials

What if, instead of a bow, we did like a tube with chemical propellant?
shit man, you're onto something there.
It would be less cost effective
if you're trying to save money just throw the bomb really hard at the helicopter. That would be the most cost effective option.
Yeah I also played ninja gaiden on the xbox.
I know a guy who plays that game just to watch the jiggle physics.
He is almost 30.
It doesn't have much in term of jiggle physics, maybe a couple of pre-rendered cutscenes with Rachel. He probably plays 2 or 3.
Too many videogames troon.
Too many troons, gamer.

You have to multiply everything by constants anyways.

Did you mean to overcomplicate it as a joke or are you just that autistic
It's literally written by AI

ITT zoomers who have not seen Rambo 3....(frick i am also zoomer come on guys everybody knows the scene with the Hind)
thats 2, zoomie
Wasnt there a game where you did it, or movie? Rambo, turok or tomb raider??

plus downwash
Unless you're fricking Ryu Hayabusa, fricking no.
>The scout heli fears the xbow
Worked for Turok
It would be really nice if frogs and wojaks were banned
