‘FDI in private security requires change in Act’

An Indian trade body has said that the Centre will need to amend the Private Security Agencies Regulation (PSAR) Act (2005) to help in implement its decision to allow foreign direct investment of up to 74% in private security agencies.
Investment in the private security sector is capped at 49% as result of the provisions under the PSAR Act (2005). Hence, the Government’s decision to allow majority foreign ownership in private security industry up to 74% would require amendments to the PSAR Act (2005).

ISRO gears up to test scramjet engine

ISRO is gearing up to test a scramjet engine based on air-breathing propulsion. The test flight of the indigenously-developed scramjet engine is scheduled to take place from the Satish Dhawan Space Centre at Sriharikota sometime in July.
Key facts:
§  The test platform, named Advanced Technology Vehicle (ATV), will comprise a scramjet engine hitched to a two-stage sounding rocket (RH- 560).
§  The vehicle has been characterised and is being fabricated at the VSSC and the ISRO Propulsion Complex, Mahendragiri.
§  The air-breathing engine will be released at a height of 70 km and ignited during the coasting phase. Apart from the hypersonic ignition at Mach 6, ISRO hopes to sustain the combustion for 5 seconds. The test is also expected to help ISRO achieve good thrust value with the scramjet engine.
§  Maintaining combustion in hypersonic conditions poses technical challenges because the fuel has to be ignited within milliseconds.
