CaDCaM’s R&D and engineering department provides aeronautical design for both, defense and commercial market
Aerospace Engineering
CaDCaM is engaged in developing UAVs, helicopters, transport aircrafts , passengers aircrafts, satellites (including their unique systems) and associated internal packaging.
Aerodynamics
In fluid mechanics, CaDCaM’s expertise is to calculate the forces acting on the aircraft, such as gravity ,drug force and so on.In addition the torque and the linear power factors are taken into account in order to calculate the angular movement of the aircraft.
Control
Systems design and improving the dynamic behavior of the aircraft.
Strength of Materials
In materials science, the strength of a material is its ability to resist an applied stress without failure. strength of materials deals with loads, deformations and the forces acting on a material. Aeronautical design deals with the physical configuration design, that is required to meet the forces acting on the aircraft during flight.
The main goal of the structural design of an aeronautical assembly is to be as easy as possible ; in order to achieve that, CaDCaM’s engineers use low safety factors (relatively to buildings or bridges) and composite materials.
Also due to the high traffic speeds there are a unique phenomenon to aeronautical structures and other phenomenon arising from aero elasticity (the relationship between the flow forces and the structure’s flexibility).
Mechanical Design with Composite Materials
Composite materials are materials composed of at least two materials, of which each material is a separate phase. The mechanical properties of the resulting composite material exceed the constituent material’s properties.
In recent years we can see a big revolution in the approach towards composite materials in aviation. With the development of carbon fabrics,kevlar fabrics and epoxy resins, the technology has been improved and expanded the use of composite materials even within the commercial sector (eg. Formula 1 racing cars contain a large number of parts made of composite materials).
Today there are whole aircrafts constructed entirely from composite materials and those aircrafts have unique features such as filtering electromagnetic radiation, high ratio of strength to weight and high stiffness.
Work process
- Presenting three design concepts
- Choosing a winning concept (PDR)
- Displaying the detailed design and analysis (CDR)
- Building a production portfolio
Prototype production - Thermal testing, dynamic testing, aerodynamic testing, functional testing
- Production portfolio update
Ready for production readiness review (PRR) - Serial production
Composite materials are materials composed of at least two materials, of which each material is a separate phase. The mechanical properties of the resulting composite material exceed the constituent material’s properties.
Stress Analyses
Stress analyses gives tensile resistance of the material, pressing, cutting, twisting and bending stress. Strength analysis examines the adjustment of a structure (or a machine part) and materials of which it is composed. Understanding the material’s strength and the load acting on it allows the engineer to select a suitable material or part of the machine and adjust the necessary measurements to be able to carry it safely, but also efficiently and economically. Strength of materials deals with the relationship between stress and distort in terms of planning stress as allowed, permitted movements and safety factors.
CaDCaM also performs structure analyses by finite element method FEM using the most advanced and internationally recognized S/W – NEI NASTRAN.
Static analyses – IMPLICIT – are characterized by relatively small movements.
Dynamic analyses – EXPLICIT – characterized by large movements and deformations – collisions, explosions, etc.
Thermal Analyses
CaDCaM specializes in thermal analyses, flow analyses, flow analyses combined with heat transfer and thermal control analyses.
CaDCaM performs heat transfer analyses and flow analysis for the military and civilian market. Analyses are performed in the field of electronic equipment, aerospace, air-conditioning, heavy duty industry, optics and medical equipment.
CaDCaM performs heat transfer analyses and flow analysis in the most advanced methods in the world – FEM (Finite Element Analysis) and CFD method.
CaDCaM uses world leading software tools for solving such problems and at the same time set as a vision to keep the customer as an integrated partner throughout the process / solution.
