Abstract

A radar-absorbing panel ( 9 ) includes a honeycomb core ( 11 ) and a lower skin ( 13 ), where the lower skin ( 13 ) is attached to the bottom of the honeycomb core ( 11 ). The honeycomb core ( 11 ) is made up of individual cells ( 15 ), which may be filled with aerogel. The individual cells ( 15 ) are approximately ½ of an inch in size with polygonal shape.

Description

technical field [0001] The present invention generally relates to methods for reducing infrared and radar signatures of vehicles. In particular it relates to the use of insulating and absorbing materials to reduce the amount of infrared radiation emitted by certain parts of the vehicle and reflected radar signals. Background technique [0002] Vehicles in military operations need to reduce their visibility to the enemy. These needs exist for all of the methods modern military forces use to detect and target enemies. Examples of such methods include visual reconnaissance, audio detection, active and passive radar and infrared reconnaissance. the need to avoid detection for aircraft such as airplanes and helicopters due to their high probability of being targeted by enemy air and ground forces using some and all of the detection methods described above Especially strong. [0003] In order to reduce the infrared signature of aircraft, several methods have been developed. T...
