Design
SRE-1 is a 555 kg capsule. It comprises aero-thermo structure, internal structure, Mission Management Unit, Altitude sensors and Inertial measurement unit, S-band transponder with unique belt array antenna embedded to ATS, power and electronics packages to support deceleration and flotation system. It also houses two microgravity payloads. It has a sphere-cone-flare configuration with a spherical nose of about 0.5 m radius, base diameter of 2 m and 1.6 m height. The parachute, pyro devices, avionics packages of triggering unit and sequencer, telemetry and tracking system and sensors for measurement of system performance parameters are placed inside the SRE-1 capsule. Parachutes for SRE capsule were provided by ADRDE.
To withstand the heat of re-entry, the cone-shaped SRE-1 has a heat shield composed of silica tiles over much of the surface, and an ablative nose cap of carbon-phenolic composite. ISRO is also working on technology to manufacture carbon-carbon composite heat shields, which, along with the silica tiles tested with the SRE-1, could find use in future reusable spacecraft such as ISRO's planned Reusable Launch Vehicle.
