Aerospace Engineering Bureau
Like automobiles, aircraft brings together numerous
fields such as engines, material sciences and electronics.
However, aircraft engineering is subject to more rigorous safety
standards than automobiles.
Aircraft tend to be larger and incorporate more equipment. The integration of this equipment and systems calls for substantial R&D personnel and time commitments.
Aircraft engineering and production therefore demands precise
engineering and stringent prior analysis and verification by
experienced engineers.
The Aerospace Engineering Bureau at ALTEN KOREA has a team of experienced engineers in fixed-wing and rotary-wing aircraft (civil and military) avionics engineering, structural engineering and analysis, and systems engineering to meet customer needs.
The aircraft development process generally proceeds in the phases of concept study - exploratory development - systems development - mass production. ALTEN KOREA’ engineering and analysis capabilities span all core areas from exploratory development to systems development.
Aircraft development procedure
Electronics Engineering
Avionics are the nervous system of aircraft. Our
avionics business is classified into circuit design, wiring
design, and electrical systems and devices (Line Replaceable
Unit, LRU).
ALTEN KOREA is the preferred electronics engineering negotiation
partner for Korea Aerospace Industries (KAI), providing
circuitry and wiring, electrical systems and equipment mounting
engineering services for the Light Armed Helicopter (LAH) and
Korean Fighter eXperimental (KF-X) projects.
Circuit Engineering
Circuit engineering is the basis for wire harness design. It involves the definition of wire harnesses with consideration of power distribution among all electrically powered equipment on an aircraft, analysis of electrical loads, and optimization of the position and facility of maintenance for each wire harness. The proper electrical operation of each component is verified, and a circuit diagram is produced for harness wiring design.
Wire Mounting Engineering
Wire mounting engineering is carried out based on a
prepared circuit diagram.
- W/H and path engineering
- Engineering of brackets for securing wire harnesses
With this process, W/H connections to each equipment in an
aircraft, interference, and maintenance facility can be
verified.
Electrical systems and equipment mounting engineering
Electrical systems connected by wire
harnesses and equipment mounts are engineered.
- Internal and external lighting
- External power
- Review, placement and securing of electrical system components
(generator and regulator, battery, and distribution systems)
Structural engineering and analysis
Whereas conventional aircraft engineering focuses on
aerodynamics and structural dynamics, the trend toward
lightweight aircraft in contemporary times has resulted in the
substitution of conventional metal with composites.
As a result, aerodynamic and structural engineering for aircraft
components subject to high loads has become ever more
important.
In addition to engineering itself, structural analysis to verify
engineering outputs has also become extremely important.
Fixed wing and rotary aircraft components are subjected to loads that vary according to wind, pressure and temperature differentials. Optimizing designs for the structural stability of wings and fuselage considering a host of variables is key.
Conceptual design and working design verification is crucial for designs to satisfy aviation specifications (FAR, MIL and individual national specifications), weight requirements, operating altitude and load factors. Countermeasures for potential fractures and deformation are also required.
Structural analysis involves static analysis and fatigue analysis to deduce optimized designs.
- Static analysis : Predicting cracks and failure of each part in response to stresses and deformation, guaranteeing structural soundness
- Fatigue analysis : The safety of the aircraft structure is verified through safe life evaluation (a means of determining component replacement cycles to avoid fatigue cracking in structures) and flaw tolerance evaluation (a means of determining the allowable scope of production and operational defects in structural components)

Systems engineering
Systems engineering is a field that encompasses all
functions necessary for aircraft operation.
Aircraft systems include : propulsion systems, flight control
systems, environmental control systems, avionics systems,
landing gear systems, electrical systems, auxiliary power
systems, hydraulic systems and weapons systems.
ALTEN KOREA has abundant experience in aircraft systems
engineering support, and is currently involved in flight
performance systems and fuel systems for the LAH project,
electrical systems for the KFX and LAH projects, and weapons
systems for the KFX project.
