초록

본 논문에서는 스마트 스킨 시제품을 항공기에 장착하고 비행데모시험을 수행하는 절차와 시험결과를 제시하였다. 통신항법용 4개의 안테나를 한 개의 안테나 내장 스킨구조(CLAS)에 삽입하였다. 대수주기 패치형 안테나를 4개의 안테나 주파수 대역을 포함하도록 다중대역 안테나로 설계하였다. 항공기에 장착하기 전에 안테나 내장 스킨구조의 요구조건은 지상시험으로 입증하였다. CLAS 스피드브레이크를 KT-1 항공기에 장착하고 2개 이상의 안테나를 작동시키는 다중 안테나 시험을 지상에서 수행하였다. 항공기에 장착된 기존 장비들과 CLAS와의 호환성을 확인하기 위해 전자파 적합성시험을 수행하였다. 비행데모시험은 4개의 안테나에 대하여 각 1회의 비행을 수행하였다. 비행 중 안테나 통신항법 신호의 작동상태와 지속성, 항공기 원형 비행 시 사각지대 유무 확인을 하였다. 안테나 내장 스킨구조의 안테나는 4회 비행데모시험 동안 기대 이상의 성능을 보여주었다.

This paper suggests an installation procedure of a smart skin prototype into an aircraft, flight demonstration test procedures and test results. Four communication and navigation antennas are embedded into one Conformal Load-bearing Antenna Structure(CLAS). Log periodic patch type antenna was designed as a multi-band antenna to cover four antenna frequency bands. The requirements of CLAS were verified by ground tests before aircraft installation. A CLAS speed-brake was installed into KT-1 aircraft and performances of dual antennas were verified as multi-antenna tests on the ground. Electromagnetic compatibility tests were conducted to check compatibility between the CLAS and all existing equipments. Flight demonstration tests were conducted by one sortie of flight test for one antenna. The activeness and continuity of communication and navigation signal during the flight, null area of antenna signal along the circling flight were monitored. The embedded antennas worked better than expected during four sorties of flight tests.
