Services

Consultancy & collaborative R&D

Services are delivered through Oravont Systems LLP for defence organisations, research institutions and industry — from feasibility studies to delivered tools.

Consultancy

Acoustic stealth & platform acoustics

Acoustic stealth design and underwater radiated noise (UWRN) control for submarines and surface platforms: acoustic signature management, sonar signal reflection and interference analysis, airborne noise estimation for crew comfort and operational readiness, and design optimisation for mast vibration and shock resilience.

R&D

AI for underwater domain awareness

Deep-learning systems for underwater acoustics: detection, classification and recognition of underwater sound sources; classical signal processing (DEMON, envelope analysis) alongside self-supervised representation learning; physics-grounded synthetic acoustic datasets for model training and validation.

Tools

Engineering software for naval design

Custom engineering software tools for naval defence applications, including SSR‑Sim (sonar signal reflection), ABNContour (airborne-noise mapping) and SMS‑Suite (shock-mount simulation).

Research & teaching

Supervision & training

Supervision of doctoral and post-graduate research at the defence-technology interface, building on faculty tenures at DIAT and MILIT, Pune; technical training and knowledge transfer in acoustics, vibration, and applied machine learning.
