Centres of Excellence : IIST
  • 10:39 AM, Friday, 23 Jun 2017

 

Scope and Objective

To perform propulsion research through advanced laser diagnostics and is envisaged to serve as (i) centre for conducting academic research in IIST that would assist ISRO activities, (ii) national facility for performing advanced research and also as a (iii) national technological development centre for aerospace organizations. 

Current Status
  • Establishment of Facilities: The laboratory  currently have the capability to perform PIV and PLIF measurements, and is  equipped with: (i) Double Pulsed Nd-YAG PIV Laser , (ii) Precision Dye Laser, (iii) Intensified CCD Camera, (iv) PIV CCD Camera (v) High Resolution Wavemeter, and (vi) Optical Components.  The basic propulsion facilities established as part of academic research projects of students are (i) Test Setup for Rocket Injector Spray Characterization from atmospheric to critical conditions, (ii) Single Element Coaxial Combustion Facility, and (iii) Supersonic Free Jet Facility 
  • Research/Project work carried out
    • CE-20 and PS4 Injector Spray cone angle, film length and droplet size distribution measurements at atmospheric conditions
    • Absolute density measurements of a jet injected at supercritical conditions to simulate supercritical mixing of hydrogen jet inside combustion chamber
    • Hydroxyl radical concentration measurements in LPG-Air Flame using non-intrusive Laser Induced Fluorescence (LIF) technique
  • Relevance to ISRO:  (i) Evaluate the ‘Mixing and Combustion’ efficiency of the fuel-oxidizer jet for any real scale engines (ii) Injector design based on characterization of jet at supercritical conditions instead of the water-air based characterization at atmospheric conditions due to the significant deviation from the true performance of the injector’s performance at actual conditions, (iii) Identify and Isolate factors causing Combustion Instability and permanently eliminate them
  • Proposed Future Work:
    • Comprehensive Cold Flow characterization of Rocket Injectors
    • Setting up hot flow facilities and MHz laser diagnostics to study the fundamental cause of Combustion Instability in rocket engine
    • Application of state of the art laser diagnostic techniques to design and develop ion propulsion thrusters

 

Scope and Objective

A NanoscienceCentre was initiated in Department of Chemistry, Indian Institute of Space Science and Technologyto support and promote the advanced research on Nanoscience and technology. The centre’s long term objectives are: (1) Undertake challenging research projects in this area to meet the future requirements of ISRO, (2) Establish comprehensive research facilities under the same umbrella to attract intellectuals across the globe, (3) Mould high quality human resources to undertake future challenges, (4) To act as nodal centre, (5) To serveas a link between industry and academia in the country

Current Status
  • Established facilities:A total budget of Rs. 330 Lakhs was sanctioned for the procurement of equipments such as glove box, nanoparticle size analyser planetary ball mill, high performance liquid chromatography, XRD analyser, plasma reactor and electrospinning machine. The procurement and installation of the above facilities except plasma reactor, XRD analyser and glove box are completed. The procurement of XRD, glove box and plasma reactor are delayed as they are identified as central institute facility. In addition to these, Solar Simulator, Atomic Force Microscope, Rheometer, TGA, DSC, DMA, IR, UV-vis, Fluorescence spectrometers, Planetary ball mill, Brabenderplasticoder, Micro compounder, Goniometer, etc. are created as department facility. These facilities are used for the research activities in the Nanoscience and Technology domain.
  • Research/Project work carried out:The first phase of the Nanosciencecentre envisages R&D activities in the broad areas such as synthesis of nanomaterials for developingnano-composites for structural and photonic applications, high efficiency photovoltaic cells and batteries and biomaterials. Research work initiated in these areas progressed well which evidenced from 17 research publications in reputed international journals and 3 patents filed with Indian Patent Office. The following projects were undertaken by this centre under IIST-ISRO project scheme.
    • Polymer nanocomposites for photonic and electronic applications (completed)
    • Intrinsically conducting polyimide composites with CNT/graphene without compromising optical properties.
    • Detection of specific explosives using surface enhanced Raman scattering (SERS)
    • Silicon-graphene oxide composite as anode materials for lithium batteries.
  • Proposed Future Work: In order to meet the proposed long term objectives, further expansion for the nano centre by adding facilities such as scanning electron microscope (SEM), transmission electron microscope (TEM), X-ray photoelectron spectroscopy (XPS), etc. is highly essential. We have identified four thrust areas of research for phase two;Energy storage and conversion,Structural nanomaterials,Bio-nano and Chemical sensors

 

Aims and Objectives

Department of Avionics is establishing the center of excellence in Virtual Reality for various space and scientific applications. The development planned in three phases. The first phase consists of desktop VR lab which consists of high-end workstation with latest graphic capabilities, 3D monitors, 3D vision-pro glasses and application software’s such as Vizard, Blender, Google Sketch, Adobe Master Suit collection, 3ds Max and Maya. The facility will be upscale by creating an immersive studio type Virtual reality center in phase 2 and 3. The proposed facility will be supported by advanced haptic devices, sensors and force feedback systems for various real life application such as navigation, fly through etc. Some objectives to establish center of excellence in Virtual Reality at Department of Avionics, IIST Trivandrum are following: 

  • Research in Space application
    • Planetary exploration
    • Indigenous software development
    • Design of VR test bed prototype
    • Virtual prototyping of space shuttle
    • Virtual walk/fly through
  • General research areas
    • Disaster modeling and simulation
    • 3-d VR visualization of compounds and chemical
    • For theoretical and nonlinear dynamical studies.
    • Developing VR teaching simulations for better understanding of the concepts in different key subjects of Avionics, aerospace, Physical science and humanities
Current status

The first phase of VR lab is accomplished in the year 2012-13. Since then a UG/PG elective course along with lab (using Vizard and Python) on Virtual Reality is being offered to 7th semester students. Every year UG/PG students carry out their internship project and Btech Project with existing facility. Work on procuring several Virtual Reality peripherals to augment their existing Desktop Virtual Reality setup is under way. These devices would be capable of being used with the Virtual Reality software development toolkit that is in place at the Desktop VR lab, WorldViz Vizard. These devices will be configured in such a way that they can be seamlessly integrated with the existing setup and can be driven from the workstations that are present in the lab. As of now one set of Virtual reality data gloves for interaction with objects in the virtual world is procured and added to existing facility.
