Departments  >>  Space Engineering and Rocketry  >  Research

The Department has been striving for excellence by pursuing R & D work in emerging areas of   Aerospace and Rocket Technologies. It is worth while to mention that the Department has successfully completed sponsored R & D Projects from premier Agencies like UGC, AICTE, DST, Ministry of HRD, ISRO, DRDO, AR & DB (Min. of Defence) etc.

The Department has also been recognized under Special Assistance Programme (SAP) of UGC and has been working on Development of a Cryogenic Propulsion System. The Department has also been supported by DST under FIST (Fund for Improvement of S & T Infrastructure) to augment Propellant Technology and Combustion Facility.

CURRENT RESEARCH ACTIVITIES

Propulsion:

1. Development of Pyro-MEMS Device for space applications

Pyro-MEMS devices for controlled energy release for micro-thrusters and micro gas generators is being developed in collaboration with Vikram Sarabhai Space Research Centre, Thiruvanthapuram.

2. Atomization of Gel Propellants using impinging and air-blast type injectors

New approach is being experimented to atomize gel propellants using different type of injection systems to achieve desired mixing and efficient combustion.

3. High Shear Rheometry for liquefying metallized gel propellants Several compositions of metallized gel propellants are being subjected to high Shear rates (>106sec-1) to study the non-Newtonian flow behaviour of these complex systems. The results are expected to provide vital inputs for achieving higher combustion efficiency in rocket engines.

4. Synthesis and characterization on Nano-catalyst for Composite Solid Propellants.

Novel Catalysts containg Cu-Co-O have been Synthesized and effective test trials with HTPB-AP based Composite Solid Propellants have been done.

5. Development of fast regression rate fuel for Hybrid Rocket Propulsion

A new hybrid fuel system consisting of HTPB-Paraffin Wax has been studied using different injectors and high regression rates have been achieved.

Aerodynamics:

Flow field investigation on supersonic air intakes: Tests are performed at different supersonic Mach numbers to investigate the start/unstart characteristics of air intakes at different off design conditions.

Drag reduction on blunt tipped bodies at supersonic speed using spikes: Different shapes and sizes of spiked tipped blunt bodies are tested at supersonic speeds to estimate the optimum performance of typical spikes. The drag force and moments are measured and stability characteristics are obtained.

High angle of attack aerodynamics of slender bodies: Aerodynamics bodies with large L/D’s have a typical characteristics of generation of side forces at moderate to high angle of attack. The estimations and alleviation of such loads are important and done in the existing subsonic wind tunnel facility of the Department.

Flow characteristics on delta and double delta wing structure: Subsonic flow field investigation on delta and double delta wing planforms are tested to understand the features of high angle of attack response. The vertical structures and its breakdown with subsequent impact on the overall load of the body are estimated.

Development of Navier-Stokes code to simulate flows over cylinder: Computational fluid dynamic gives a complete flow simulation with enormous amount of data around the body of interest which can not be visualised through any other methods. These data supplement the experimental observations and gives the details of flow to better understand the features.
