Fully implemented model of KO-50 kerosene powered defroster.
KO-50 kerosene powered defroster is installed on a right hand side outside cargo compartment to the fore of fuel tank and is covered by special nacelle.
KO-50 kerosene powered defroster is designed to heat up the air supplied to helicopter compartments.
KO-50 controls are located at the pilots’ right electric board.
The TV-1 thermometer designated for control of air temperature in passengers’ compartment is located at the right dash board.
It’s recommended to turn on the KO-50 in “heating mode” having OAT/FAT below +10°C while engines running on the ground or using ground electric power, in flight at any time for except autorotation mode.
There are no limitations running KO-50 in “ventilation” mode.
1. Start up and usage of defroster in automatic temperature adjustment mode.
To start defroster in mentioned mode it is needed to:
1. Turn on DC power.
2. Turn on "KO-50" switch.
3. Set temperature selector to +30°С.
4. Set mode selector switch to "автомат"(auto) position.
5. Press and hold for 2–3 seconds the "запуск"(start) button.
Fuel preheater starts to function, a yellow annunciator panel “ПОДОГРЕВ ТОПЛИВА”(fuel preheating) lights up. When fuel temperature reaches 70 ±50°С (preheating time 35 ±15 seconds) fuel preheater turns off automatically, yellow annunciator panel “ПОДОГРЕВ ТОПЛИВА” goes dark. Simultaneously with fuel preheater shut down heater ignition and electric fan systems gets turned on. To annunciator panels lights up: yellow – “ЗАЖИГАНИЕ”(ignition), green – “ОБОГРЕВАТЕЛЬ РАБОТАЕТ НОРМАЛЬНО”(defroster functions normally). The annunciator panel “ЗАЖИГАНИЕ”(ignition) should go dark not later than after 2 minutes counting from "запуск"(start) button gets pressed. Defrosted is to be considered functioning when yellow annunciator panel “ЗАЖИГАНИЕ”(ignition) goes dark and green annunciator panel “ОБОГРЕВАТЕЛЬ РАБОТАЕТ НОРМАЛЬНО”(defroster functions normally) stays lit. After defroster start required temperature for helicopter compartments to be set using temperature selector switch.
2. Start up and usage of defroster in manual temperature adjustment mode.
Set “ЗАЛИВКА –ПОЛНЫЙ РЕЖИМ –СРЕДНИЙ РЕЖИМ”(priming – maximum mode – half mode) mode selector switch to “ПОЛНЫЙ РЕЖИМ”(maximum mode) position (having OAT/FAT lower than -13°С) or “СРЕДНИЙ РЕЖИМ”(half mode) (-13°С to +15°С).
To start defroster in mentioned mode it is needed to:
1. Turn on DC power.
2. Turn on "KO-50" switch.
3. Set temperature selector to any position.
4. Select “ПОЛНЫЙ РЕЖИМ –СРЕДНИЙ РЕЖИМ”(maximum mode - half mode) mode using switch located on a right dash board.
5. Set mode selector switch to "ручной"(manual) position.
6. Press and hold for 2–3 seconds the "запуск"(start) button.
Further equipment functioning it similar to start up in automatic mode.
Defroster function in ventilation mode.
When using defroster for cabin ventilation in summer time turn on KO-50 switch and “ВЕНТИЛ.”(fan) switch to on position.
Turning off KO-50 defroster.
To turn off defroster set mode selector switch to neutral position. Green annunciator panel “ОБОГРЕВАТЕЛЬ РАБОТАЕТ НОРМАЛЬНО”(defroster functions normally) goes dark. But fan still stays on. Air supplied by fan eliminates fuel from combustion chamber, cools down calorifier. Fan gets turned off by automatic temperature sensor when temperature of air coming from defroster drops below +50°C.
I wish You all to have a nice and warm flight in winter conditions!
