A method for slowing the heat transfer rate to a flow facing part of an object exposed to a high total enthalpy fluid flow flowing in a direction approximately perpendicular to that part, including the step of recessing that part. There is also provided apparatus for protecting a heat sensitive instrument (26) in an object (20) from a high enthalpy fluid flow impinging on the instrument in flow facing relationship, and to which the instrument must be exposed due to the nature of its desired functioning, including an essentially unvented recess (22) defined in or near the tip or the leading edge of the object, the instrument being disposed in the recess.
