Centre for Civil Aircraft Design & Development
The Centre for Civil Aircraft Design & Development (C-CADD) is the nodal point of CSIR-NAL, with a mandate to play a lead role in the design and development of small and medium sized civil aircraft, optimally utilizing the available resources. It was set up in the year May 1998.
C-CADD is currently involved in the development and certification of a 14-seater light transport aircraft (SARAS) and 5-seater general aviation aircraft (CNM-5) after having successfully certified the all composite Hansa-3, a 2-seater ab initio trainer for pilot training in flying clubs. Saras is expected to usher in a vibrant civil aircraft industry in the country in the coming years. Also in the pipeline is the development of a new generation Hansa aircraft, the Hansa-NG, offering improved features and state-of-the-art display system to meet the current requirement of flying training clubs.
Core Competencies that exist in C-CADD include Aircraft Design, Configuration aerodynamics, Wind tunnel model design, fabrication and testing, Airframe structural design and stress analysis using conventional as well as state-of-the-art finite element tools, System design and analysis comprising of flight controls, pneumatic, hydraulic, fuel power-plant, environmental control and electrical systems, Kinematic design and analysis, Aircraft Prototype Manufacturing and Inspection, CAD/ CAM, Digital mock-up, kinematic simulation, Tool and Jig Design, CNC programming and Design validation, Manufacturing of components (machined and sheet metal) for airborne application, Manufacturing of precision wind tunnel models, Dimensional Metrology and Certification of Assembly Jigs, Calibration of dimensional measuring instruments and machine tools, Aircraft Assembly, Integration and Flight Testing, Structural Assembly and integration, System level and aircraft level testing, Power plant testing, Electrical Looming, Quality Assurance and Control, Flight Testing and Telemetry Operations, and Flight Data Analysis.
The newly built Golden Jubilee Aircraft Hangar of C-CADD has important facilities such as Bonded Stores, Cold Stores, Tool Crib, Heat Treatment Furnace for Rivets, Sealant Application, bench rigs for LRUs, Aircraft Looming, Flight Test Instrumentation, Air Handling Unit, etc. to undertake aircraft activities. The Hangar has adequate built-in space to facilitate integration of three Saras category aircraft at the same time.
Expertise of C-CADD extends to design, development and manufacture of test rigs to prove concepts in a new aircraft design cycle. An Engine Test Bed has been designed, commissioned and used extensively used for validating modifications on the engine propeller combination, testing of EICAS, throttle sensitivity studies etc.
CSIR-NAL has both Design and Production approval under CEMILAC/DGAQA. Expertise exists in C-CADD to develop documented quality system for aircraft design and manufacturing as per requirements of regulatory agencies viz., DGCA, CEMILAC and DGAQA.
Apart from these activities, C-CADD also operates powered hang gliders in its possession and provides first hand training to interested staff and scientists in ab-initio flying training. C-CADD has also successfully developed and demonstrated an airboat using an air propulsion system that can be deployed for the cleaning up weeds from polluted water-bodies.
