Is it possible to put multiple accelerator grid in ion engine instead of one? So we will get higher exhaust velocity and benefit for us right? or is there any disadvantages?
Here is a paper from NASA that analyzed ion wind propulsion.RocketAstro said:Is it possible to put multiple accelerator grid in ion engine instead of one? So we will get higher exhaust velocity and benefit for us right? or is there any disadvantages?
Yes, multiple accelerator grids can increase the thrust of an ion engine. The accelerator grids are responsible for accelerating the ions, which in turn generate thrust. By adding more accelerator grids, the ions can be accelerated to higher velocities, resulting in a higher thrust output.
The number of accelerator grids that can be put in an ion engine depends on the design and size of the engine. Some ion engines may have only one grid, while others can have multiple grids. The number of grids also depends on the specific application and desired thrust output.
Using multiple accelerator grids in an ion engine can increase the thrust output and improve the efficiency of the engine. This can result in faster acceleration and longer operating times for spacecraft. Additionally, multiple grids can provide more flexibility in the control and direction of the ion beam.
One potential drawback of using multiple accelerator grids is that it can increase the complexity and cost of the ion engine. More grids mean more components that need to be designed, manufactured, and maintained. Additionally, the added weight of the grids may impact the overall weight and size limitations of the spacecraft.
It is possible to retrofit an existing ion engine with multiple accelerator grids, but it may not be practical or cost-effective. The design and structure of the engine would need to be modified to accommodate the additional grids, which could be a complex and expensive process. It may be more feasible to design and build a new ion engine with multiple grids from the beginning.
