Material selection, structural analysis, and thermal performance of carbon-fibre airframes under Indian field conditions.
Material Selection Criteria
Agricultural UAVs operate in harsh environments — high temperatures, humidity, dust, and exposure to chemicals. Carbon-fibre composites offer an ideal balance of strength, weight, and chemical resistance. This paper presents our material selection methodology and test results.
Structural Analysis
We present finite element analysis (FEA) results for the Samrudhhi-10L airframe under various load conditions, including maximum payload, gust loads, and emergency landing scenarios. Safety factors exceed 2.0 across all load cases.
Thermal Performance
Indian summer temperatures can exceed 45°C, affecting both structural integrity and electronic component performance. Our thermal management approach combines passive cooling through composite material selection with active cooling for critical components.
