Project 7 - Compact Diesel-Electric Submarine
Project 7 is a small, dark-blue submarine built around the philosophy of "zero unnecessary automation". Sub doesnt have massage chair and big touchscreen with button "make cool". You are alone in this can. And you can trust only yourself, even a simple depth holding can just went crazy and you die because of system think its 15km under you, but in reality you have 5 meters of your hopes and dreams.
***Habitability***
The conning tower contains diving suit, 2 medkits, surface and underwater welding torches and fire extinguisher.
Bridge houses all primary control systems: Helm, ballast and electromotor propulsion.
***Ballast and Depth Control***
Four ballast tanks (2 forward, 2 aft) with individual controls.
Flooding via direct seacock opening. De-watering via slow pumps.
Depth control:
Off: Surface hold.
On (Negative number): Absolute depth hold (+-8 meters)
On (Positive number): Altitude hold above seabed.
"Straight Control" switch bypasses depth hold and unlocks W/S.
***Sonar and Navigation***
Passive sonar: Manual control of yaw and FOV. Displays both bearings (horizontal and vertical (Yaw and Pitch)), target distance, signal strenght (target noise) and detecting indicator. Max is 1km.
Active sonar: Detects up to 16 targets, displaying azimuth and elevation for each target. Manual ping. Max is 60km.
Helm: Compass ball, RPS, speed in knots and kilometers per hour, vertical speed is m/s and depth with seabed.
Lightning and Observation: Camera, navigational lights and spotlight.
***Power***
Primary engine - diesel. Requires manual startup, oxygen and fuel throttles, clutch and generator clutch.
Gas storage: 3 medium tanks of air, 2 small tanks of primary oxygen and 1 small tank for backup (emergency) oxygen.
Electric motor - Emergency/backup propulsion. Less eficient than diesel but quiter (but not silent).
Monitoring: RPS, engine and coolant temperature, both oxygen tanks pressure (primary and backup), fuel consumption (L/min (unstable at efficiency rps: 20-27)), fuel remaining (from one tank), battery charge and battery rate.
***Ventilation***
Gas monitors: O2, CO2 and pressure of both compartments.
Two compressors: Turbocompressor (electric), diesel compressor. Diesel compressor is alot better.
Exhaust of foul air overboard.
Individual ventilation valves for bridge and utility.
***Guides:***
Diesel startup:
First open fuel and air valves in the utility (behind dials), then turn on radiator, set the throttle valves to needed proportion (for atosphere air - 2:1, for oxygen - idk) and hold starter for about a second. When RPS is above 2 unhold starter and connect clutch.
Ventilation guide:
First make sure that you have more than 1 atmosphere in all air tanks, then turn "Pressurize ventilation", open valves above you (Pressurize Bridge and/or Pressurize Utility) and slowly open Ventilation valve (Throttle lever). If you need to decrease pressure - open Pressure valve (on the right wall, dark blue valve) and turn "Pump Out Air".
Underwater diesel guide:
First close "Engine Air" (and "Ventilation Air") valve in the conning tower, then go to utility, find blue valve "Engine Oxygen" (above the fuel ratio dial) and correct the Air Throttle lever (Pure oxygen is more efficinent than atosphere air, thats it) until Air:Fuel ratio will be 14.
Submerge guide:
First fill all ballats until half of the dials, then close Engine Air and Ventilation Air in the conning tower and done! Set depth on the "Depth" keyboard on the helm seat and turn on "Depth Hold" or turn on "Straight Control" and push nose down with W.
Thats all. Work is still in progress, please comment your ideas or fixes and ill try to fix and improve it.
