Analysis for Effect of Angle of Attack on Coefficient of Lift of Wing Structure
2024-06-01
2024-26-0450
For a wing, the angle of attack is essential in creating proper splits to incoming winds, even under high velocities with larger distances from the separation point. In the case of a group of wings, each wing is then mentioned as a wing element, and each wing is strategically positioned behind the previous wing in terms of its vertical height and its self-angle of attack to create maximum lift.

High Frequency Unsteady Pressure Measurement System for Aerodynamic Characterization in Launch Vehicles
2024-06-01
2024-26-0432
Unsteady pressure measurements are crucial for understanding dynamic pressure distribution changes in fluid flow fields and over object surfaces, revealing insights into complex flow phenomena induced by shock waves, vortices, boundary layer interactions, and flow separation. While ground-based wind tunnel tests have conventionally provided these insights, this paper presents an on-board system for real-time unsteady pressure data acquisition.

Development of Deployment Mechanism for RAMBHA-LP Payload Onboard Chandrayaan-3 Lander
2024-06-01
2024-26-0455
The probe deployment mechanism consists of the Titanium alloy spherical probe with a Titanium Nitride coating on its surface to achieve a constant work function, a long carbon-fiber-reinforced polymer boom, a double torsion spring, a dust-protection box, and a shape-memory alloy-based Frangibolt actuator for low-shock separation. The entire mechanism weighed less than 1.5 kilograms. The system had undergone a sufficiently large number of sub-system level and system level tests in ambient, dynamic, and thermo-vacuum environments experienced in an interplanetary mission.

INLS 3U Unipod Nano Satellite (CubeSat) Dispenser System for 3U Class Satellites
2024-06-01
2024-26-0458
The actuation time, separation time, electrical specifications, separation velocity and rates are designed at par with the internationally available commercial systems. ...This necessitated the need for a low shock separation system that does not have mass attached to the separated satellite. Development of Nano satellites with mass of the order of 1 to 24 kg has become popular among scientific/ academic institutions for carrying out scientific experiments. ...The Unipod separation system successfully flown first time in PSLV C56 Mission for the deployment of three foreign satellites namely Nulion, Galassia-2 and SCOOB II.
