Technical and Aptitude Questions with Answers

Question 1: Aeronautical Engineering

Q: What is the primary advantage of a swept-back wing design in high-speed aircraft?

A: Swept-back wings reduce drag at high subsonic and supersonic speeds by delaying the onset of shock waves. The sweep angle effectively reduces the thickness-to-chord ratio as seen by the airflow, decreasing wave drag and allowing higher critical Mach numbers.

Question 2: Mechanical Engineering

Q: In gas turbine engines, what is the function of the stator blades in a compressor stage?

A: Stator blades (stationary blades) in a compressor serve to:

1. Convert velocity energy from the rotor into pressure energy
2. Redirect airflow to the optimum angle for the next rotor stage
3. Prevent swirl in the airflow, ensuring efficient compression

Question 3: Quantitative Aptitude

Q: A plane travels 600 km against the wind in 2 hours and returns with the wind in 1.5 hours. What is the speed of the wind?

A: Let plane speed = p km/h, wind speed = w km/h Against wind: p - w = 600/2 = 300 With wind: p + w = 600/1.5 = 400 Adding equations: 2p = 700, p = 350 Wind speed w = 400 - 350 = 50 km/h

Question 4: Electrical Engineering

Q: What is the significance of the constant speed drive (CSD) unit in aircraft electrical systems?

A: The CSD unit maintains constant frequency (400 Hz) output from the engine-driven generator despite varying engine speeds. This is crucial because aircraft systems require stable frequency power supply, and engine RPM varies during flight phases.

Question 5: Logical Reasoning

Q: Find the next term in the series: ACE, BDF, CEG, DFH, ?

A: Each letter in the term moves forward by 1: A→B→C→D→E, C→D→E→F→G, E→F→G→H→I Next term: EGI

Question 6: General Awareness

Q: Which HAL manufacturing division is responsible for the production of the LCA Tejas?

A: The LCA Tejas is primarily manufactured at HAL's Bengaluru Complex, specifically at the Aircraft Division and the newly established LCA Tejas Division in Bangalore.

Question 7: Electronics Engineering

Q: What is the primary purpose of the transponder in aircraft avionics?

A: A transponder (transmitter-responder) receives radio signals from air traffic control radar and automatically transmits a reply containing the aircraft's identification code and altitude. This enables ATC to identify and track aircraft accurately.

Question 8: Quantitative Aptitude

Q: The ratio of investments of A and B is 3:4 and the ratio of their profits is 2:3. If A invested for 8 months, for how many months did B invest?

A: (Investment × Time) ratio = Profit ratio (3 × 8) : (4 × B's time) = 2 : 3 24 : 4x = 2 : 3 72 = 8x x = 9 months

Question 9: Materials Science

Q: Why are titanium alloys preferred for aircraft engine components?

A: Titanium alloys are preferred because they offer:

1. High strength-to-weight ratio
2. Excellent corrosion resistance
3. Ability to withstand high temperatures (up to 600°C)
4. Good fatigue resistance
5. Compatibility with composite materials

Question 10: Logical Reasoning

Q: Statement: All aircraft are vehicles. Some vehicles are electric. Conclusion: I. Some aircraft are electric. II. All electric things are vehicles.

A: Neither conclusion follows.

• Conclusion I is invalid because aircraft being vehicles doesn't imply they are electric.
• Conclusion II is invalid because "some vehicles are electric" doesn't mean "all electric things are vehicles." Answer: Neither I nor II follows.

Interview Tips

• Know HAL's Product Portfolio: Research HAL's current projects including LCA Tejas, Advanced Light Helicopter (ALH) Dhruv, Light Combat Helicopter (LCH), and Dornier 228. Understanding these platforms demonstrates genuine interest.
