Computer for Helicopter
Does anyone know which vendors and types of CPU processors are used onboard helicopters?
That really depends what helicopter you are talking about, generally they are a few generations of tech old and they would be custom systems since standard IO doesn't exist on helicopters. They want to make sure that the program they are running on the hardware works flawlessly and it takes a few years to ensure that so the CPUs are never modern and never upgraded.

Yep, good point. I'm referring to the UH-60 Blackhawk.
The chips are using for military purposes have nothing to do with the chips are used for pc’s, servers. They have differed mass density (durability), power consumption, water resistance, heat resistance for hard conditions, tough weather.
In high altitude the air is thinner an air cooled pc doesn’t operates good enough so getting a laptop to a helicopter you risking to burn it if the air pressure drops below 1000 hPa.
So forget any thoughts you make and keep it closed until you land.
The military uses electronics with embedded CPU.
See following article which talks about embedded systems and a list of companies that the military contracts with.
The following are Intel's embedded CPUs:
The first link you gave makes it really clear there is no room for NH-D14, massive coolers in a guidance system anyway so comparing them with the second link you gave is a joke.
The 8086 processor is used to some missles as we speack but is not the same in watts and not the same in mass density not the same in assembly code commands they have build in inside! They have diffrent structure from top to bottom anyway (is a very Big issue) they are RISC processors mostly not CISC, what i mean is the large part of the code is implemanted in hardware for faster output....
Intelligence services are using Cray machines, nothing as you know it in architecture, cooling again.
PS becarefull Jaguarskx fbi will arest us for exporting military details to public hehehehe. Some corporations are not allowed even to shell, export out of country, these chips so nobady be able to hack them,etc
Giatrakis is right. Military applications generally use processors that are tailored to the application, not what happens to be available on the market.
Many of the embedded devices that they use may be based on existing designs such as Intel's x86 architecture but the actual finished product is substantially different from what you would find in a desktop PC.
IBM is one of the main providers of digital electronics for the US Military. IBM's AP-101 avionics computer has been in use for decades and remains in use today in thousands of military aircraft. It was specially designed to be hardened against the elements and fault-resistant. It works and there's no need to replace it.
The Space Shuttle used 5 radiation hardened AP-101 computers. 4 were run concurrently and one was in backup. Due to the impact of radiation on memory (even radiation hardened memory) all 4 computers ran the same calculations to ensure absolute reliability. The cockpit controls in the Space Shuttle were later upgraded to 386s in the 1990s but the avionics were run on AP-101s
The International Space Station uses radiation hardened Intel 386SX processors with the Intel 387 coprocessor.
The Hubble Space Telescope uses a radiation hardened 486
