Avionics Flashcards
Learn critical avionics components.
What is the primary purpose of the “Comm” Flight Computer?
The “Comm” flight computer acts as a bridge between HLS and Orion, and also runs all the cabin systems.
What is the primary purpose of the “Deck” Flight Computer?
The “Deck flight computer runs all the systems in the garage and airlocks, and isolates the vehicle from all systems driven by the “Main” computer.
What is the primary purpose of the “Main” Flight Computer?
It runs all the critical vehicle propulsion and control systems.
What is the primary purpose of the “Gateway” Flight Computer?
IT connects to the Ground Infrastructure through the Quick Disconnect (QD).
How many computer strings does the V4H flight computer?
3
What is the Fault Tolerance for this hardware for LOM?
1FT to LOM
What is Fault Tolerance to LOC?
2FT to credible catastrophic hazards that result in LOC.
Where do the flight computers reside?
Comm FC is in forward nose, Deck and Main computers are in Garage, and Gateway computer is in Aft.
What is the box I/O for the flight computer
3x RS-422 (1 per string); 6x 1000Base-T Ethernet connections (2 per string)
What is the primary purpose of the Sensor DAQ?
To sense vehicle temperatures and pressure sensors
What is the Fault Tolerance for the Sensor DAQ?
1 FT to any single network, power or microcontroller fault (requires 2 of 3 strings to work for voting)
What is the Box I/O for the Sensor DAQ
3x 100Base-TX Ethernet inputs; 18x RTD
What is the primary purpose of the Stage Controller?
To actuate valves, read pressure transducers and RTDs.
What is the box I/O for the Stage Controller?
2x100Base-TX Ethernet inputs; 12 x Valve drivers; 6x RTDs
What is the FT of the Stage Controller?
1 FT to power, network, and microcontroller faults.
