Technical Round Materials-Aeronautical Engineering-Free Download

Question 1. What Is Spice? Where Was It Developed?

Answer :

The full form of SPICE is Simulation program with integrated circuit emphasis.This is the widely used analog simulator, which was developed at electronics research lab of California University.

• Question 2. What Are The Three Tactical Elements Of Electronic Warfare?

Answer :

Electronic warfare has three main elements:

ES – Electronic support – This has high passive acquisition intelligence about friend and foe

EA – Electronic attack – that has passive and active denial of RF spectrum

EP – Electronic protection - protects friendly personnel and assets by active and passive techniques.

• Question 3. What Are The Main Areas In Aviation?

Answer :

* Artificial intelligence

* Aircrafts and parts

* Advanced materials, composites and specialty metals

* Computers, electronic components, and systems

* Fighters and attack aircraft

* Government defense policies and goals

* Lasers

* Navigation controls and guidance systems

* Ordinance and Military vehicles

* Computers, electronic components, and systems

* Aviation electronic/Avionics

* Robotics

* Satellites

* Search and detection equipments

* Strategic defensive initiative

* Sensors and instrumentation

* Ships

* Space vehicles and commercialization of space

• Question 4. What Is The Requirement To Become A Professional Engineer (pe) In The Field Of Aerospace?

Answer :

Professional Engineer license is required for people who aspire to go in as officially approved engineer. The design specification is done by self¬employed people or working in small business. General aerospace engineers work for government or for big companies and hence few people are not very keen on becoming PE�s. To become a PE one has to pass an exam on fundamentals of engineering which takes alot of hours to gruel and work under a licensed PE for about four years. In addition, they have to grow through a principle and practice of engineering exam, which requires about 8 hours.

• Question 5. Explain The Day¬to¬day Responsibilities Of Aerospace Engineering

Answer :

Each job profile even in aerospace industry differs from others. Mainly in aerospace, there are two branches or field. One is aeronautical and other is astronautical engineering.

Question 6. Explain The Differences Between Aeronautical Engineering And Astronautical Engineering

Answer :

Aeronautical engineering deals with vehicles which operates in the atmosphere Aeronautical engineering deals with vehicles operating in space.

Aeronautical engineering works on tunnel tests, analyzing flight test data,manned space flights, planning future space missions, spacecraft operations,designing and testing robotic systems, developing new propulsion system,computing optimum flight trajectories, developing communication systems for distance space probes and designing new rockets.

Astronautical engineer includes designing power systems for spacecraft structure, developing communications systems for distant space probes, developing hardware skills for operations in spacecraft, designing and testing robotic systems, developing new propulsion systems and computing optimum flight.

• Question 7. Does The Knowledge Of Mathematics Of Science Is Required To Get Into Aerospace Engineering?

Answer :

The basic understanding of Math is important, as it is not used at all the time during the course of aerospace engineering. One should have a basic understanding of mathematical definitions and knowledge on computers is very important as the computer programs will help in doing simple calculations and verify the results are reasonable. However, on the science front it is very important to have a very good understanding on various subjects like dynamics and mechanics in physics, strong emphasis on chemistry, electromagnetism.

For a good engineer one should know how law of forces makes things happen. In addition, if you are good at physical sciences when opposed to life sciences like biology you will be a fit candidate for aerospace engineering

• Question 8. What Do You Understand By Aerodynamics/performance Analysis?

Answer :

Aerodynamics / performance analysis in military programs include responsibility like analyzing aerodynamics impacts which effects from external modifications, developing mission profiles based on requirements from the customer, performance data of the mission which includes take off and landing details, en route and mission data performance. Analyze the configurations using the dynamics, which are fluid and computational. Additional task may include support for wind tunnel planning for test flight. Documentation, test support, data analysis should be done on regular basis. Co ordination of aerodynamics with multi discipline teams and data should be provided for support flight management system or mission planning software.

• Question 9. What Will Be The Responsibility Of The Spacecraft Operations, Dynamics, And Controls?

People working on these areas as aerospace engineers should have familiarity and exposure to NASTRAN and MATLAB with knowledge on space environment and modeling of flexible dynamics. These aerospace engineers will be responsible to work in the areas of structural control, momentum control, line of sight (LOS), spacecraft mission design, control of space boards payloads, operational engineering.

• Question 10. Explain About Stress Analysis?

Answer : People working on these areas as an aerospace engineer should have familiarity and exposure to NASTRAN and MATLAB with knowledge on space environment and modeling of flexible dynamics. These aerospace engineers will be responsible to conduct stress analysis on metallic and composite structures. NASTRAN, IDEAD, Oracle, and PATRAN proficiency level is required. Their duties also include on aircraft, which are metallic and composite structures. This includes and understanding of control surface stiffness and loop calculations, finite element modeling (FEM), fatigue testing requirement and analysis.

• Question 11. What Is The Testing Done In Aerospace Engineering?

The testing of small rocket engines and entails development by researching on aerospace. They are responsible to perform and experiment on laboratory facility, which is dedicated to aerospace. One should be capable of solving problems by applying knowledge by solving problem of the research done. They will be working with technical team of researchers and they should have ability handle projects alone
