Abstract
An air flow transducer for measuring rate of air flow into an engine having a propensity to backfire includes a rotor with vanes disposed to intercept the air flow. The vanes are formed of low density plastic and affixed to a rotor. The trailing edges of the vanes are shaped to direct forces occasioned by backfire pressure waves to hold the vanes to the hub.
