궁금해하시는 분들이 많던데, 현재 KAAV-II 시제차량 포탑은 완성된 게 아니고, 포탑 내/외부의 주요 지점에서 사격 시 발생하는 충격량을 계측하기 위해 제작된 것입니다. 따라서 구성품들은 목업이고 실제 작동하진 않습니다. 레이다의 경우에는 아이언피스트 APS의 aCHR 레이다로 목업을 제작한 것으로 추정되고, 실제로는 ADEX 2025에 전시된 한화시스템의 APS가 통합될 가능성이 큽니다.

patreon.com/posts/analysis-o… I've uploaded an "Analysis of KAAV-II Prototype Vehicle" to Patreon. KAAV-II exploratory development ('18.10~'25.06) program focused on developing marine propulsion technology, body transformation technology for marine operation, variable suspension system technology, and lightweight armor technology, as well as materializing operational concepts and analyzing/setting optimal military required performance through land maneuver prototype, marine maneuver prototype, and vehicle operability confirmation tests. System development program is scheduled to commence in 2027 and continue until 2032.

patreon.com/posts/yonsei-aer… KTP1400 is turboprop engine to be mounted on MQ-105K MUAV Block-II. It was developed through "Medium-Altitude Performance-Improved Turboprop Engine Technology ('21.07-'25.08)" project, and plans to acquire Initial Flight Release (IFR) through "Propeller-Driven Aero-Engine Prototype Development and Engine Certification Demonstration Technology ('24.12-'28.12)" project. Max-continuous power achieved 1,400 hp, which is about 17% improvement over PT6A-67A (1,200hp). Also, HAF4500 turbofan engine is under development utilizing KTP1400 core engine through "Development of Core Technology for 4,500lbf-Class High-Bypass Turbofan Engine for Electrified Aircraft ('26.04~'29.12)" project. HAF4500 is 4,500lbf, high-bypass turbofan engine (BPR 4 ). It features application of Inter-Shaft Rotor and integration of ISG capable of generating 100kWe. ▶ Engine length 1,405mm, width 686mm, height 830mm. ▶ 2-stage Centrifugal compressor, Reverse-flow Annular combustor, 2-stage Gas generator turbine, 2-stage Power turbine, 2-stage Reduction gear ▶ Air mass flow 3.3kg/s, OPR 14:1 (Take-off 12.6:1 / Max. 19:1) ▶ SFC : 0.46 lb/shp/hr ▶ Max. rotational speed : Gas generator (Ng) 38,000 rpm, Power turbine (Np) 23,000 rpm

patreon.com/posts/kf-21-figh… Compared to estimated figures, it was confirmed that mass production program cost rose significantly due to exchange rate and supply chain issues, etc. Including auxiliary equipment, CSP, M/F, facility construction, etc., unit acquisition cost for KF-21 Block-I fighter increased by 5.74% from initial projection. In 80-unit subsequent program, acquisition cost per Block-II fighter grew by approximately 10% over Block-I.
