A battery`s internal resistance is determined by (OCV = Open Circuit Voltage, CCV = Closed Circuit Voltage)
- IR = (OCV – CCV)/ i.
- IR = (OCV + CCV) / i.
- IR = (OCV - CCV) / V.
zeiadzidan asking:
why
Power-off stall versus power-on stall:
- Power-on stalling speed is higher because the propeller slipstream increases the effective airspeed over the wing
- Power-on stalling speed is lower because the vertical component of thrust helps support the aircraft weight, reducing the lift requirement
- Power setting has no aerodynamic effect on the stalling speed regardless of engine type or thrust line orientation
kspyroglou asking:
How can that be true? Thrust is a horizontal component acting parallel to the aircraft’s line of direction.
With an increase in the amount of flap deployment, the stalling angle of a wing
- remains the same.
- increases.
- decreases.
