The joints in aircraft structures are the most problematic places in terms of static strength, life time, tightness, weight and economic parameters. Impulse technologies and tools for their implementation offered by us, can significantly improve the technical and economical parameters of assembly processes and structures integrally. The technologies and tools have been developed at the aircraft manufacturing processes department for:
The feature of impulse technologies is the high energy intensity and high initial velocity of the working tool, resulting in increased workability, improved quality and increased stability of the results.
Impulse technologies have several advantages:
The department has developed various models of manual pneumoimpulse tool for riveting, lock-bolts setting, burnishing and hole punching in structures made of light aluminum and titanium alloys, steels, composites and hybrid structures. Created impulse tool has the following advantages:
In order to reduce the cost of experimental studies and costs for the search of the multifactorial experiment rational parameters, the devices design refinement and its compatibility with the assembled product the advanced computer system have been used, such as ANSYS, Abaqus, LS-Dyna, Solid Works, etc.
