Experimental and computational investigation of pressure field over inner surface of jet tab fixed to the supersonic nozzle exit sponsored by Aeronautics R&D Board/ DRDL

• The controls of the flying vehicle are achieved through various techniques. One is the conventional method is the use of control surfaces which are found to be easier but the surfaces contribute to increase in drag of the vehicles.
• The other methods includes use of Thrust vector control (TVC), movable nozzle etc. The TVC is achieved by the use of jet tabs fitted to the nozzle exit.
• The jet issued from the nozzle acts on the inner surface of the nozzle and thus creates a force on the surface. The force acting on the tabs can be used to control the flying vehicle in a required direction.
• The project focuses on the estimation of the force on the tabs due to the jet issued from the C-D nozzle. The test will be carried out at supersonic Mach numbers 2.0, 2.3 & 2.5
• The tab configuration will be varied based on tab lengths and tab sector angles. The tab lengths are considered to be X/D = 0.15, 0.3 & 0.5 and the tab sector angles are 600, 900 & 1200.

WIND DRIVEN AIR STORAGE SYSTEM SPONSORED BY NATIONAL INSTITUTE OF WIND ENERGY (NIWE)

FOUNDATION DESIGN & BOLTS

• The rotor of the wind turbine drives the compressor and the excess energy from the wind turbine is stored locally as compressed air in a pressurised storage tank.
• Piston displacement air compressor is used to store and extract energy, which operates nearly at isothermal conditions to have maximum efficiency.
• A 5 HP oil lubricated compressor is mounted in the wind turbine nacelle which is located on the top of a 20 m lattice tower.
• A rotating union that is located in the nacelle couples the compressor and the storage tank of 10000 litres capacity that is situated within the tower and the stored air is regulated by pressure regulators for feeding required loads.
• The safety of the system is ensured as when the tank is full, the piston will not be able to compress further and the rotor is stopped.
• The rotor directly drives the compressor and when the pressure exceeds the tank set pressure, then the rotor will not spin. A heat sinks panel and a radiator (if required) for the compressor will be employed.
• To reduce the problems associated with thermal rise the compression chamber made up of Aluminium die castings with fins will be employed.
• An actual prototype of the following model is planned: 5 kW capacities [Class III] Wind Turbine for 5 HP Compressor. A 1 kW Generator is coupled to 5 kW Wind Turbine for feeding lighting loads.
