modifying various flow channels in the housing of fig2 as well as changing the position of the temperature sensing element will change the flow over the temperature sensing element the heaters can also be changed in power or location to realize a uniform offset between actual static temperature and the measured temperature in the tests the number and size of the boundary layer bleed ports 40 and the exit of air from the boundary layer bleed ports through the channel 41 can be changed to adjust the heating effect the size of the orifice 24 can be changed and openings 30 can be resized to alter the airflow other structural changes can be made for varying the airflow or the temperature sensing element can be mounted closer to the heater the strut 14 according to the present invention is heated with electric resistance deicing heaters shown schematically at 35 at desired locations along the strut leading edge and in other desired locations on the walls of the housing as shown in fig2 in addition to the deicing heater needed there is an extra heater section 35 a on an interior wall of the strut the heater 35 a is on tube 26 and will affect the temperature of the air sensed by temperature sensing element 38 which is mounted in the flow passageway 26 a shield 37 can be removed or or made to only partially surround the temperature sensing element as shown there is a large opening at the front of the shield 37 in order to increase the effect of the heaters.
