CAREER EPISODE 1
1) Introduction:
[CE 1.1]
This career episode is based on the project presented at the technical seminar organised by the IARE (Institute of Aeronautical Engineering) in collaboration with the Department of Aeronautical Engineering, Hyderabad, India. The project was titled “Aircraft Thermal Analysis,” and I worked on it to fulfil the requirements of my bachelor’s degree. The project was commenced in Month/Year and completed in Month/Year.
2) Background:
[CE 1.2]
Over the past few years, the thermal management of the aircraft has gained a lot of importance because of the following main reasons:
- To provide a comfortable ambient environment to the crew and passengers
- To allow aeroplane systems and cargo to operate in an acceptable operating environment
- To protect aircraft structures from thermal threats.
On top of that, the management is also required to ensure that both crew & passengers are neither too cold nor too warm, regardless of the OAT (Outdoor Ambient Temperature), which can exceed 70 °C throughout a flight. Extensive research on commercial aircraft shows that poor cabin temperature control leads to numerous passenger issues and eventually causes a loss of valuable customers and a drastic reduction in annual revenue for an airline. In addition, in military aircraft, pilot distress due to extremely poor temperature control can negatively impact crew performance.
Therefore, based on these identified problems, it was decided to implement aircraft thermal management to ensure occupant comfort, the safety of structural operations and systems, and longevity in normal operation, as well as survival in the event of failure. In this project, a thermal analysis was conducted to propose an economical, lighter-weight thermal design for an aircraft.
[CE 1.3]
I carried out a thermal analysis of the aircraft by performing the following main tasks:
- Analyzed the impact on aircraft due to differences in the outside and internal ambient environment.
- Studied the effects of solar heating and internal headloads on the aircraft.
- Proposed the modifications to reduce the impact of identified problems on the commercial aircraft, i.e. development of the ECS (environment control system).
- Suggested innovative solutions to remove excessive system heat or structural temperatures by using a heat sink mechanism.
- Developed the final report, which showed the analysis in detail.
- Involved in the project meetings and managed the project work.

CAREER EPISODE 2
1) Introduction:
[CE 2.1]
The second career episode is the description of the major project, which was conducted to fulfil the requirements of my Bachelor of Technology in Aeronautical Engineering, completed at the Institute of Aeronautical Engineering, Dundigal, Hyderabad. The project was titled “Airfoil Stall delay using Synthetic Jets” and was conducted during the time frame of Month/Year and Month/Year.
2) Background:
[CE 2.2]
Over the past few decades, extensive research has been conducted on synthetic jets, which are currently used in a wide range of applications, from separation & turbulence control to the cooling of electronic and propulsion systems. Also, such jets are characterized by the fact that they are synthesized entirely from surrounding fluid, as well as produce no net mass into an external flow. Fortunately, all these facts have eliminated the need for fluid circuitry and enabled compact, self-contained designs that integrate both actuation, power, and control electronics.
Therefore, in this major project, we have decided to study the behaviour of a wing with & without a synthetic jet in the wind tunnel to ensure that a wing made by using synthetic jets will surely have a higher stall angle as compared to the normal wing. Similarly, it would delay the separation of the boundary layer.
[CE 2.3]
The following duties were assigned to me:
- Performed a literature survey to study the previous research conducted on the synthetic jet, NACA0015 airfoil, actuators, and optimum location of the synthetic jet on the airfoil to control stall, etc.
- Involved in the fabrication and testing of the wing with & without a synthetic jet.
- Used the wind tunnel made of teak wood and waterproof plywood to test the developed wing.
- Performed the testing on the wing in the wind tunnel and observed its performance.
- Discussed the experimental results in detail.
- Called frequent team meetings to brainstorm over the complex issues and also discussed the work status.
- Designed the working schedule and was also responsible for creating the final thesis document.
CAREER EPISODE 3
1) Introduction:
[CE 3.1]
The last career episode is based on my eighth-semester mini-project “Aircraft Anti-Hijacking System Using RFIDs”, which was conducted to complete the key requirement of my Bachelor of Technology degree in Aeronautical Engineering from the Institute of Aeronautical Engineering, Dundigal, Hyderabad, Telangana. I started working on this project in Month/Year and completed it in Month/Year.
2) Background:
[CE 3.2]
Nowadays, many types of research have been conducted to develop a system to prevent aircraft hijackings. In this time of need, we also decided to propose a secure system comprising a Raspberry Pi PC & control program coded in Python. With the help of this system, an aircraft’s manual control will get disabled immediately whenever any unusual condition occurs persistently beyond a pre-defined limit.
Generally, this condition will appear above the predefined time of 10s, and at this point, it will immediately turn on the 2 authorized RFID tags and take the aircraft’s control by triggering an autopilot beyond 10 seconds. Furthermore, this system will not permit any manual input, i.e., disabling the system, because this can create a vulnerability.
[CE 3.3]
I was responsible for performing the following main tasks:
- Studied the techniques previously implemented to eradicate the hijacking problems and how effective they were in terms of preventing the attempts.
- Developed the flowchart, which showed the working of the system.
- Selected the components and then assembled them to develop the hijacking system.
- Prepared the required setup and then tested the system’s functionality using Python code.
- Tested the system and discussed its results.
- Monitored the activities of my teammates and lent a hand to complete the tasks on time.
- Documented the project details and gave presentations to the supervisor.
- Scheduled the project meetings and also encouraged my team to participate in all meeting discussions. Receive free CDR samples from AustraliaCDRHelp.Com.
