#2789: WasPitot

In some places, wasps are making nests in the pitot tubes of aircraft.

Not knowing one’s airspeed is a dangerous condition to be in, so today’s invention offers a solution.

Normally an aircaft pitot tube measures airspeed indirectly by the movement of a small diaphragm (red). In order to periodically clean out any nascent wasps’ nests, a small bottle of compressed air (orange) would be connected to the pitot tube using 2 electronically controlled valves.

The blue one closes to protect the diaphragm and then the pink one opens to allow air from the tank to flush the tube.

Any residual blockages would be indicated by an increase in pressure at this valve.
