Of course! An to start, one needs to find examples to work from. Else, would you like to start from scratch and work on pure imagination?
To start on that, lets take the Mi-26 Halo Helicopter. Mentioned as the heaviest helicopter in the world; With a starting weight of 28200kg (with no additional weight), going as far as 56000kg for maximum takeoff weight. Any additional weight would potential cause problems or prevent takeoff.
Though of Russian origins and a odd placement in a area like New London, it still gives potential information on how you’d be able to code additional helicopters, both of existing designs or custom.
With this being a working design for heaviest Helicopter, coupled with information on weight + lift, we could determined the overall limit players could strive for when it comes building helicopters. I guess you could say a hard cap to put it bluntly, a limit on how heavy a helicopter could be or how much additional weight they could pickup from loot, before liftoff becomes unfeasible.
On other device topics, there is also the gryocopter, a light, minimalist design, considered the predecessor for the helicopter.
A the Zapata Flyboard Air TM, a real life “Hoverboard” and Green Goblin impression. Commissioned from the French Military as a assault platform; Yet due to the noise generated and the challenges of learning to fly this, it is consider not ready for application.
Now in a universe that is statistical advance in some forms, you can see how this design could have implementations within this intended form.
To concluded, this page is in part intended to explore candidates for flying devices and their design applications, to further understand their limitations and potential use.
Unless the intended goal here is to build a singular flying device called, “Flying object 001”, with no references of any particular design and no chart on the how and why it can fly.
