Upgrading of Aerospace Technology

Delhi 

The Union Minister of State (Independent Charge) of the Ministry of Development of North Eastern Region (DoNER), MoS PMO, Personnel, Public Grievances & Pensions, Atomic Energy and Space, Dr Jitendra in a written reply to a question on the reasons for the failure of PSLV C-39 mission on the 31st August, 2017 said that the 41st flight of PSLV (PSLV-C39) that took place on August 31, 2017 with Indian Regional Navigational Satellite (IRNSS-1H weighing 1425 kg) could not reach the designated orbit, due to non-separation of Payload Fairing (also known as heat shield) during the 2nd stage of the flight. The root cause of the failure was understood after analysing the various flight and ground test data in more detail. For the Payload Fairing separation to happen successfully, the horizontal and vertical jettisoning system needs to function. Based on the flight data, it was observed that the command for horizontal and vertical jettisoning system was successfully issued. Though the horizontal jettisoning system functioned normally, there was malfunctioning of the vertical jettisoning system, due to which the Payload Fairing did not separate. The cause for the malfunctioning was the non-initiation of detonation in the vertical jettisoning system.

In a reply to a question on what steps would the Department proposes to constantly upgrade the aerospace technology the Minister replied that Department constantly undertakes various Research & Development activities, technology developments and experimental missions towards technological upgradation and achieve significant improvement in the performance of the launch vehicles, satellites and ground systems. The recent experimental missions that were successfully accomplished were the Reusable Launch Vehicle Technology Demonstrator in May 2016 and the first experimental flight of a sub-scale Scramjet engine in August 2016, towards reducing the cost of access to space. The Department has also undertaken technology development and upgradation in the propulsion systems to increase the payload capability of the space transportation systems such as the development of a Semicryogenic engine, high thrust liquid engines and Cryogenic stages with increased propellant loading. The Department has also undertaken the development of high thrust electric propulsion systems towards an all-electric communication satellites to replace the relatively heavier Chemical propulsion system.

On a question on budgetary allocation Minister said that the budget allocation of during the FY 2017-18 is 9093.71 Crore. 20% of the total allocation for are deployed for R&D activities.

As per the report The Space Economy at a Glance 2014" published by OECD (Organisation for Economic Cooperation & Development), India stands at sixth position among the space faring nations, in terms of space budget as percentage of GDP.

He also said that the products developed by the Department undergo rigorous design reviews, qualification tests and acceptance tests before they are inducted into the systems. ISRO has a well-defined Quality Assurance mechanism that certifies the products before they are inducted into the various systems for its space missions. The procedures for quality assurance and quality control are well documented and disseminated to the in-house and external work centres in order to ensure the product reliability.
