Task 1.1

The aircraft is equipped with two engines. One engine produces 98 kN of thrust. The aircraft weighs 65 tons. What is the aircraft's thrust-to-weight ratio?

T = P/G

P = 2P1

G = mg

P = 2 · 98 kN = 196 kN

G = 65000 kg · 9,81 m/s2 = 637650 H

T = 196000 H / 637650 H ≈ 0,307

Task 1.2

Plastic waste weighing 1,000 kg was processed by thermal pyrolysis at 480°C. The yield of liquid hydrocarbons by weight of the plastic waste was 75%. The liquid hydrocarbons contained 35% of the kerosene fraction. What is the mass of the kerosene fraction?

Mass of liquid hydrocarbons: 1,000 kg × 0.75 = 750 kg.

Mass of kerosene fraction: 750 kg × 0.35 = 262.5 kg.

Task 2.1

The airplane's wingspan is 36 m. The wing area is 123 m². Determine the aspect ratio of the airplane's wing.

The aspect ratio of the airplane's wing is λ = b^2/S

λ = 36^2/123 = 1296/123 = 10,5
