Curing Method

Filament winding and fiber placement are low-cost, fast, and suitable processes for manufacturing composite grid structures. Resulted structures are high quality products. They have the advantage of carrying heavy structural loads as well as light structural weight. Composite Grid Structures (CGS) are manufactured with varying geometries such as circular (cylindrical and conic) and flat. They are applied in hightech industries including aerospace industry. In this paper, the manufacturing processes of these structures and their various aspects (including winding method, mandrel material and curing method) are reviewed and compared in detail.

Review Study

Indian flying corps and Israel Aerospace Industries (IAI) forged long standing military ties, Israel aviation enterprises keeping up their strong position as best-in-class UAV manufacturers for both civilian and military use and supplying the Indian military with advanced UAV frameworks. IAI has provided IAF with a sum of 176 Israel-made automatons including 108 IAI Searchers and 68 unarmed Heron-1 airships for observation and surveillance missions including an armada of IAI Harpy rambles. With the expanding request of India's military associations, for example, the DRDO, Aeronautical Development Establishment (ADE), the National Aerospace Laboratories (NAL), Hindustan Aeronautics Limited (HAL) have been creating UAVs with ISR, focusing on, and weapon direction abilities. The first trip of the Rustom-2 model on 16 November 2016 was a turning point for India. This work shows the correlation of the Indian and Israeli UAVs created depending on their main capacities and execution qualities.
