Aircrafts (esp., fast moving aircrafts) require environmental information (air data products) like wind speed, wind direction, temperature, pressure, and density of air, in addition to information pertaining to angle of attack (AoA), and angle of side slip (AoSS) for properly controlling the instabilities of the aircraft and also to facilitate safe navigation.
There is a growing demand to replace the Pitot-static tube technology currently being used by the Aerospace Industry on board all aircrafts with Laser Based remote Technologies for monitoring air data products which are fundamental necessities for safety, navigation and stability of aircrafts.
  • taraNi (a photonic system) was envisaged as a compact, lightweight, cheap, direct detection optical system that can directly measure wind speed and direction, density, pressure and temperature of a body of air, ahead of a moving aircraft - whose operative conditions may vary from speeds ranging from zero to hypersonic, from flight altitudes varying from sea level to 18 kilometers, from flight paths across sea and land. The outcomes of the measurements are to be comprehensive air data products (including AoA, AoSS).
  • taraNi is a molecular optical air data system designed and developed indigenously involving novel and innovative techniques, as an alternative to the systems which are under development in the western world.
  • Finally, the prototype of taraNi was tested and proved at NAL's Supersonic Wind Tunnel Facility for wind speeds up to 2.0 Mach. The system needs to be flight tested once the aircraft (AMCA) is ready.
  • The remotely operable, portable light weight system (taraNi) which can be easily integrated on board any platform is highly sensitive, accurate and again free of the constraints associated with the many available / under development systems and technologies around the world.
  • Tarani is compact incoherent detection type optical equipment capable of directly measuring air data parameters viz. air speed and direction, density and temperature of the undisturbed air mass (free-stream) ahead of the aircraft.
  • The measured parameters, shall typically include True airspeed, rate-of-climb, static density, static air temperature, Angle-of-Sideslip.
  • From the measured parameters, other parameters of interest shall be computed or derived based on known relationships. These derived parameters shall typically include density ratio, pressure altitude, calibrated air speed, dynamic pressure, differential pressures related to angle-of-attack and angle- of-sideslip.
  • The sensor outputs shall be compatible with RS422 interface to connect to Air Data Computer / Digital Flight Control Computer / Vehicle management computer
