Design and development of spark plug part no sp 87PA of AL-31FP aero engine

Source

Source summary

Develop the specified SP-87PA spark plug for the AL-31FP aircraft engine, preserving fit in the main combustion chamber. The source specifies at least 1,000 flying hours of life and a maximum 0.28 kg mass. Its description of ignition operation does not constitute proof that a proposed replacement meets those requirements.

Protecting Humans Engaged in Sewage Cleaning - Protective gears, equipment and other solutions for ensuring the health and safety of humans engaged in sewage cleaning

Develop protective clothing, equipment and related solutions for sewage-cleaning workers when human intervention is required. Protection from hazardous gases and other exposures, alongside worker dignity, is central; this is a separate ask from mechanising the cleaning itself.

Two-Way Audio Communication

Support low-latency, two-way audio in IP cameras and related communication devices using VEGA/SHAKTI RISC-V cores. The source calls for efficient encoding, decoding and streaming, with examples including AAC, Opus and G.711, to balance bandwidth and audio quality in voice and video communication. Noise suppression, echo cancellation and filtering, plus battery-sensitive embedded operation, are also specified. It also calls for noise suppression, echo cancellation and filtering, with battery life as an embedded-device constraint.

Carbon fibre winding (CFW)

Abridged source description: establish domestic carbon-fibre winding capability and access to suitable fibre for an existing rocket-launcher barrel assembly. The source identifies an already established metallic-liner process but unavailable local winding technology and export restrictions on fibre. Weapon-manufacturing recipes, material selection and performance targets are intentionally omitted.
