[HowTo] make acceleration of Projectile Movement Component work without HomingTargetComponent

I’m making a fighter plane game, the missiles on plane are made by Projectile Movement Component, I want the velocity to accelerate from 0 even without HomingTargetComponent setting.
But when I set the Velocity to 0, Initial Speed to 0 and the Max Speed to 80000, it won’t move at all.
I wonder if there’s any posible way to do so, do I have to manage the velocity myself?

BTW, when launching missiles I use the same object direct on the plane actor with setting active to false, is it better to spawn another missile in the same location or not?
