Founder, Breshev Engineering · Creator of AURA Engineering Platform · Gas-Static Bearings · Rotor Dynamics · Engineering Software
Approximately 18 years across mechanical systems, precision engineering, CAD/CAE, simulation, testing and software product development — concentrated into AURA, a working platform for gas-static bearing and high-speed rotor decisions.
Research-to-product position
AURA connects direct calculation and inverse synthesis of gas-static bearings — including adjustable conical supports — to manufacturable spindle geometry, rotor dynamics and release evidence.
Its differentiation is the continuity of the engineering state: requirements, physics, geometry, dynamic response, validation basis and decision authority remain part of one traceable workflow.
Research focus
The work is deliberately integrated: bearing coefficients are not treated as isolated catalogue values, and rotor results are not separated from geometry, operating state or the evidence needed for an engineering decision.
02
Adjustable conical supports
Geometry, clearance control and load-path behaviour in adjustable non-contact spindle architectures.
03
High-speed spindles and rotors
Support coefficients, critical-speed screening, unbalance response, orbit and stability indicators.
04
Manufacturable geometry
Connecting the physical model to drive, shaft, tool, support and tolerance definitions that can be built.
05
Experiment and validation
Test-state provenance, model–measurement comparison and explicit validation envelopes.
06
Evidence-gated software
Separating a physical screening result from the authority to freeze, release or attribute field behaviour.

Technical publications
A Balancing Result Is Not Plane-Free
Independent technical article on tolerance, measurement and correction planes; machine capability; assembly transfer; and release authority. Not presented as peer reviewed.
AURA Engineering Platform
Public methodology and product record for gas-static bearing synthesis, rotor workflows and evidence-gated decisions.
Current research questions
State transfer
What can a warm or factory-test result prove after clearance, thermal state and boundary conditions change?
Coefficient authority
How should bearing stiffness and damping provenance travel into rotor-dynamic and release decisions?
Manufacturing transfer
How do tolerances, balance planes and assembly state alter the authority of a component-level result?
Open validation surface
The proprietary solver remains closed. The public surface makes methodology, reference cases, evidence status and decision boundaries inspectable through DOI records and a versioned validation registry.
Collaboration formats
One-case benchmark
Compare one defined bearing or rotor case with assumptions and provenance recorded.
Spindle acceptance map
Translate requirements, operating state and measurement evidence into explicit acceptance boundaries.
Test-to-model validation
Align configurations and conditions, compare results and identify the next highest-value test.
Measurement evidence annex
Preserve apparatus, repeatability, planes, configuration and what the result is allowed to support.
API or workflow integration
Connect a controlled engineering calculation or evidence object to an internal toolchain through a scoped interface.
Joint technical work
Develop a benchmark, application note or validation case with clear authorship and claim boundaries.

Bring one defined engineering question
Machine type, speed range, support architecture, available geometry and the decision the evidence must support are enough to start a focused technical conversation.
