6. What are the safety recommendations required while maintaining aircraft?

Ans:

The safety recommendations are required while dealing with the accidents and the inquiry of the aircrafts. The recommendations needed are as follows:

• CAA (Civil aviation authority) examines the applicability of self-certification of aircraft engineering and verifies the criticality of the tasks that need to be performed on the system. They also check the system for further services without doing any functional checks.

• Review of the system takes place to interpret the single components of the aircraft that is vital in its design.

• Reviewing of the quality assurance system and the reporting methods take place to encourage more better designs to be provided for the use.

• Reviewing the need to, introduce a format of job description and grades that is being provided to the engineers and managers.

• Providing a mechanism for an independent assessment to carry out the work audit and operations can be performed smoothly.

7. What is Aerospace Engineering? Who are Aerospace Engineers?

Ans:

Aerospace Engineers are involved in all aspects of aeronautics (working with aircraft) and astronautics (working with spacecraft). They conduct research, and design and develop vehicles and systems for atmospheric and space environments. These engineers often specialize in one of many areas such as aerodynamics, propulsion, flight mechanics, orbital mechanics, fluids, structures, guidance & control, and computation.

9. Explain the differences between Aeronautical Engineering and astronautical engineering?

Ans:

Aeronautical engineering deals with vehicles which operates in the atmosphere Aeronautical engineering deals with vehicles operating in space. Aeronautical engineering works on tunnel tests, analysing 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.

10. What will be the responsibility of the spacecraft operations, dynamics, and controls?

Ans:

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

11. What is the testing done in aerospace engineering?

Ans:

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.

12. What are the objectives of Aerodynamics?

Ans:

Aerodynamics deals with the theory of flow of air and it has many practical applications in engineering. There are some objectives that are being used in aerodynamics and these are as follows:

• It is used to predict the forces, moments and heat transfer from the bodies that is moving through the liquid.

• It deals with the movement of wings or use of the wind force. This way it requires the calculations to be done for the aerodynamic heating of the flight vehicles and the hydrodynamic forces applied on the surface of the vehicle.

• It is used to determine the flows that are moving internally through ducts. This way it makes the calculations and measurement of the flow properties that is inside the rocket and jet engines.

13. What are the sources involved in aerodynamics?

Ans:

There are two sources that are involved in the case of aerodynamics forces and moments that are on the body. These forces are as follows:

• Pressure distribution: this is the distribution that is over the body surface

• Shear stress distribution: this is the distribution that is over the body surface These sources are for the body shapes and it doesn’t matter how complex they are. The mechanism that is being used to communicate with the bodies that is moving through a fluid. Both the pressure (p) and shear stress (?) having the dimension force per unit area. This helps the movement of the body through the fluid.

14. What are the major sectors involved in aircraft maintenance?

Ans:

There are two major sectors involved in aircraft maintenance and these are handled by certifying technician in the field of support and maintenance. These are divided into two sectors as:

• Category B1 (mechanical): these are the maintenance technicians that have good knowledge regarding the working of airframe, engine, electrical power systems and equipment. It also requires additional knowledge of aircraft structures and materials.

• Category B2 (avionic): this deals with the integrated knowledge of aircraft equipments, electrical, instrument and radar related systems. They undergo proper training to handle the aircraft equipments and gain practical experience to deal with day to day activities.

15. What is the main source of power in aircraft?

Ans:

The main source of power is the hydraulic motor that is provided by the scheduled service and involves operations that allow technicians to solve complex system problems. This setup required certifying the technician to operate all the system the same way as it is been done with one system. The hydraulic motor needs to be operated the same way and maintained in a proper way. The alignment need to in synchronization with the aircraft auxiliary power unity (APU) before anything is done with the aircraft positioning. A standard need to, be followed to maintain the aircrafts and its parts equipped and working.
