유럽도 F-35A 핵심기술 이전엔 난색

노르웨이공군의 미국제 F-16에 독일제 IRIS-T 공대공 미사일이 통합된 과정에 대한 글입니다.

먼저 양쪽이 상대방의 정보를 공개하거나 쓰지 않는다는 Proprietary Information Agreement이란 계약서에 서명하고 같이 Interface Control Document란 문서를 쓴다고 합니다.

Interface Control Document는 상대방의 장비의 인터페이스에 뭐가 들어가고 뭐가 나오는지 정의하고, 그 장비가 안에서는 어떻게 돌아가고, 성능은 얼마나 나오는지는 "블랙 박스"로 취급되어 (The internal workings and performance of each party's equipment is treated as a black box as no information about internal workings is provided) 서로 알려주지 않는다고 합니다.

전투기 제작사가 미사일 제작사에게 알려주는 것은 다음과 같습니다.

- captive carry loads
- G forces
- air loads
- 미사일을 쏠 때, 그리고 전투기가 착륙할 때의 충격에 영향을 주는 buffet, aircraft roll/pitch/yaw 특성
- grounding interface
- control data interface and bandwith
- electrical power availability
- aero flow field characteristics
- launcher mounting provisions
- aircraft INS/GPS accuracy (if needed by the missile)
- datalink frequency range and bandwidth (if needed) 등등

미사일 제작사가 전투기 제작사에게 알려주는 것은 다음과 같습니다.

- size/shape aero model to determine drag during captive carry,
- missile weight,
- CG,
- electrical power and data requirements (power on sequence, safe/arming commands, seeker activation/slewing, lock-on tones, fuse programming, A/C position reference upload/update by hardline and/or datalink),
- a simple kinematic model that describes limitations for launch,
- rail mounting requirements,
- missile RF emissions so airframe systems aren't blinded for those occasions where the missile seeker goes active on the rail

결론은 neither party obtains enough data to reverse engineer the other's equipment라고, 서로 상대방의 장비의 비밀은 알 수 없다는 것입니다.

마지막에는 Joint Test Plan이란 것에 따라서 테스트 계획하고 모을 데이터를 정의합니다.

---------------

There is no issue integrating IRIS-T on F-16 because both are NATO weapons and performance is covered by treaty and .gov security classifications. Violate .gov security and contractor personnel can go to prison and the company can be barred from current and future classified projects (It's the Sword of Damocles that no contractor wants to violate).

Integration of complex engineered systems (airplane and missile) is done by the 2 parties signing a "Proprietary Information Agreement" and jointly authoring an "Interface Control Document".

A PIA is a contractually enforceable agreement that states neither party will disclose or utilize the other's data. A government security classification can be applied on top of a PIA. Big time lawsuits and/or prison time can result if violation occurs.

An ICD defines all the goes-intos and goes-out-ofs for the interface of each party's equipment. The internal workings and performance of each party's equipment is treated as a black box as no information about internal workings is provided. In the case of a new missile installation, the airframer would provide specifics about: captive carry loads/G forces/air loads/buffet, aircraft roll/pitch/yaw characteristics that could effect missile launch, landing shock, grounding interface, control data interface and bandwith, electrical power availability, aero flow field characteristics, launcher mounting provisions, aircraft INS/GPS accuracy (if needed by the missile), datalink frequency range and bandwidth (if needed) and the like.

The missile manufacturer would provide: size/shape aero model to determine drag during captive carry, missile weight, CG, electrical power and data requirements (power on sequence, safe/arming commands, seeker activation/slewing, lock-on tones, fuse programming, A/C position reference upload/update by hardline and/or datalink), a simple kinematic model that describes limitations for launch, rail mounting requirements, and stuff like missile RF emissions so airframe systems aren't blinded for those occasions where the missile seeker goes active on the rail.

As you can see, neither party obtains enough data to reverse engineer the other's equipment. The airframer does not get the missile's blueprints and the missile manufacturer does not get the airplane's blueprints.

Later in integration, a Joint Test Plan is produced that define the test program and data parameters to be collected. The data only covers the launch of the missile. It does not repeat missile performance tests that were done as part of missile development.

아니 왜 저렇게 찌라시들을 양산해 낼까요?

XBX KXX기자 신났네요. 이젠 FMS 가지고도 시비네..ㅡㅡ
