Question 1: How do the principles of "positive" and "negative" dynamic stability affect an aircraft's behavior after a disturbance?

Which action should you take?

Choose only one option

Negative stability always leads to uncontrollable flight, while positive stability limits maneuverability

Both positive and negative stability result in the aircraft stabilizing over time

Positive stability results in excessive oscillations, while negative stability is desirable for maneuverability

Positive stability leads to the aircraft returning to equilibrium, while negative stability causes divergence from equilibrium

Question 2: In terms of thermodynamic efficiency, which cycle is most commonly used in modern jet engines?

Which action should you take?

Choose only one option

The Rankine cycle

The Stirling cycle

The Brayton cycle

The Otto cycle

Question 3: How does increasing the aspect ratio of a wing affect the aircraft's roll stability?

Which action should you take?

Choose only one option

Increases roll instability

Improves roll rate

Decreases the maneuverability

Increases the turning rate

Question 4: In designing electrical power systems for satellites, what is the most critical factor in power distribution?

Which action should you take?

Choose only one option

Ensuring the system can operate autonomously without human intervention

Reducing the complexity of the system to save on manufacturing costs

Ensuring power is available to all subsystems, particularly during eclipse periods

Minimizing the weight of the power system

Question 5: What is the impact of wing-fuselage interference on the aerodynamic performance of an aircraft?

Which action should you take?

Choose only one option

It has minimal effect on the aircraft's lift and drag

It reduces the overall drag by improving flow over the fuselage

It can cause a significant increase in drag and reduce stability

It increases the lift-to-drag ratio due to flow separation

Question 6: Which system monitors and diagnoses electrical faults in aircraft?

Which action should you take?

Choose only one option

Fault Detection System

Electrical Load Analysis

Power Distribution Unit

Central Maintenance System
