FM OVERVIEW:
We are currently in the process of connecting all other instruments to the corresponding bus routes.
All instruments will be connected correctly according to the circuit diagram and will react accordingly. This includes power supply, light intensity, magnetic switch behavior and instrument failure.
We are also almost finished integrating the drag/wind forces from all external components of the helicopter.
The downwash MEDUSA-FM is also 50% finished.
This was stopped at the moment as we first checked the altimeter. Speed Indicator and Compass had to be coded.
MEDUSA RORTOR SYSTEM:
The rotor system was implemented accurately. This also includes the rigid rotor head directed 3° forward and ~1.5° forward to the right.
Current coding:
We are currently in the process of adapting the Sight Line Indicator Compass to the Magnetic Compass.
Since the Magnetic Compass shows the real position of the helicopter, the Sightline Compass may differ in certain circumstances.
There is a display field in the Sightline Indicator Compass that shows when you need to adjust the compass disk. This is indicated by a "+" symbol and a "ball" symbol.
With a switch you can then calibrate the disc (indexed rotation of the compass disc) and adapt it to the magnetic compass.
ELECTRIC BUS:
The Electric Bus is finished and is just waiting to receive signals from the remaining devices.
The Electric Bus was 100% implemented according to the circuit diagram.
Progress news for April 2024
FM OVERVIEW
We are currently in the process of connecting all other instruments to the corresponding bus routes. All instruments will be connected correctly according to the circuit diagram and will react accordingly. This includes power supply, light intensity, magnetic switch behavior and instrument failure.
We have also almost finished integrating the drag and wind forces from all external components of the helicopter. The downwash MEDUSA-FM is 50% done as well.
Further progress on the flight model is blocked until the altimeter, speed indicator and and compass are done code-wise.
FORCES, WIND and DAMAGE
Since the MEDUSA system monitors the entire helicopter, all forces such as penetrating wind, stabilizers, OAT (Outside air temperature), damage and blown parts are taken into account. For example, if a rotor blade is broken or missing, the MEDUSA rotor task will take this into account and recalculate the flight behavior.
MEDUSA ROTOR SYSTEM
The rotor system was implemented accurately. This also includes the rigid rotor head directed 3° forward and ~1.5° forward to the right.
Currently we are in the process of aligning the line of sight indicator compass to the magnetic compass. Since the magnetic compass shows the real position of the helicopter, the line of sight compass may differ in certain circumstances. A "+" (plus) or a circle indicator will tell you if you need to adjust the line of sight compass.
You will be able to calibrate the disc (indexed rotation of the compass disc) and adjust it to the magnetic compass with a switch.
ELECTRIC BUS
The electric bus is finished and is just waiting to receive signals from the remaining devices. It's 100% implemented according to the circuit diagram.
WEAPON SYSTEM
The weapon system is currently in our backlog and will be implemented when the majority of other systems are complete. This is one of the last tasks for MEDUSA. As always, this will be implemented exactly according to the circuit diagram.
This includes, but is not limited to:
SELF TEST
Wire cut cases
Power problems
The weapon system communicates with the line of sight indicator, YAW control and the current position of the helicopter.
YAW CONTROL INSIGHTS
When YAW CONT is on and the "SIGHT LINE" ON switch on the collective is pressed/held, the helicopter will always follow the left/right angle of the sight unit (105° left/right). However, the pilot always has control over the helicopter and must ensure that he is always within the line of sight limit (line of sight Indicator Limits -> 3° left/right). If the conditions are not met, the HOT can't be fired. If the HOT is in flight and the pilot deviates from the 3°, the HOT's communication wires are cut.
If steering inputs are too hard, the hydraulic system switches from System 1 to System 2 (Displayed on the warning panel). This automatically switches the YAW CONT magnetic switch to OFF. In this mode the helicopter is no longer able to follow the periscope.
This entire process is monitored by the MEDUSA HYDRAULIC task and the MEDUSA POWER SUPPLY task.
