The Velocity of spark ignition in aircraft design refers to the speed at which the air-fuel mixture flows through the engine’s induction system. This parameter is vital for understanding the engine’s combustion process and performance. The formula for velocity (V) can be defined as:
– V is the velocity of the air-fuel mixture (in meters per second, m/s).
– mdot is the mass flow rate of the air-fuel mixture (in kilograms per second, kg/s).
– ρ is the density of the air-fuel mixture (in kilograms per cubic meter, kg/m³).
– A is the cross-sectional area of the induction system (in square meters, m²).
