CE 1.2 Project Background
CE 1.2.1 Characteristics of the project
The project of supersonic business jet was my first major project in aeronautical
engineering career. This project has focused on the supersonic aircrafts and their features.
Various significant features and characteristics were identified and designed proficiently in
the project. The design decisions that are taken have eventually revolved for the final
configuration. Weight analysis on the basis of mission profile and requirements was done.
The range of the supersonic business jet was solely identified in the process. Moreover, this
project even covered the arrangement of the aircraft with a list of components and 3 View
System. Engine configuration was the next significant characteristic of this particular project.
CE 1.2.2 Objectives developed for the project
The project of GARG-001 Supersonic business jet consisted of various important
objectives. They are as follows:
 To design a supersonic business jet.
 To identify the design flaws in business jet and make it better for the users.

CE 1.2.3 My area of work
My major area of work was to design the supersonic business jet. I designed the entire
aircraft after considering the extremely high profile consumers. The design flaws were
identified substantially by me and even documented the project report. My next area of work
was to analyze the weight of the design of supersonic business jet. Our mission profile was
based on the requirements of FAR 25 with the help of business supersonic category.

CE 1.2.5 My responsibilities throughout the project
I had various important responsibilities in this project. My first and the foremost
responsibility was to make the design of the supersonic business jet. For the purpose of
designing the supersonic business jet, I undertook various duties like analyzing the weights of
the components. I knew that weights of the components are extremely important in aircraft
and hence I made sure that I successfully execute these duties. My second responsibility was
to design the landing gear of the aircraft. For this purpose, I reviewed the system significantly

and came up with the idea to select the review configuration. Since the aircraft could easily
achieve extremely higher velocities, the landing gear was supposed to clear from damages,
and it would have been better in terms of reducing induced drag. My other important
responsibilities included documenting the project report completely and assist my project
supervisor in this specific project.
CE 1.3 Distinctive Activity
CE 1.3.1 Engineering knowledge and skills applied in the project
Several aeronautical skills and knowledge were applied in the project by me. The
most important and significant skills like critical thinking, mathematics, complicated problem
solving, operations analysis and systems evaluation were applied in this project. The learning
strategies skill was also applied here. Moreover, knowledge related to physics, designing,
computers, engineering and technology were even applied in the project of supersonic
business jet. My knowledge regarding production processes, raw materials, quality control
and various techniques was even successfully applied in this particular project. I even applied
my core skill of time management and coordination in the project of supersonic business jet.
CE 1.3.3 Comprehending the Theory of Project
Supersonic jet has the ability to fly much faster than the rest of aircrafts. The
aerodynamics of the supersonic flights are known as compressible flow since the
compression with the shock waves created, helps to travel much faster than sound. The
aircrafts that can fly at speed more than Mach 5 are termed as hypersonic aircraft. For the
weight analysis, we got some of the values in our project. These values were nothing but
phases that were expressed in respect to the fuel fraction. The starting values of engine, taxi,
take off, landing engine shutdown, descent and climb was 0.99. The starting values of cruise

1 and cruise 2 was 0.786 and reserve loiter was 0.913. We got the maximum range of
4200nm and the total payload that we calculated for our project was 5450.75 lbs.
For the equation of the two takeoff cases,
(T/W)TO=0.00596*(W/S)TO at CLmaxto=1.6
(T/W)TO=0.00475*(W/S)TO at CLmaxto=2.0
We got these two equations by estimating the value of (w/s) in the two intersection
points. The two equations of landing cases, are straight line parallel to the y-axis, each line
represent a different CLmaxL:
(w/s)to= 58.866 at CLmaxL=1.8
(w/s)TO=71.950 at CLaxL=2.2
Drawing the cruise path which usually has an equation of (T/W)TO=(1/(W/S)TO)^.5
Having the 5 different paths, our plane will have place as it’s marked on our matching
chart, which will let us calculate the thrust required for takeoff, and we tried to match it with
the thrust of an engine, and therefore we employed the P&W JT8D-219 which perfectly fit.

Figure 2: GARG-001 Fuselage Layout
The GARG-001 has a maximum capability to carry a payload of 6000 lbs which can
be altered to suite many different scenarios these are some of the basic components in the
aircraft, some of the following don’t figure the calculations as they are fixed and not
interchangeable.
18 people (13 passengers and 5 crew) weighing 165 lbs = 2970 lbs
Food/Beverages = 220 lbs
Baggage = 918 lbs
A payload of 4,108 lbs was assumed in order to achieve 1892 lbs extra for
transportation of cargo i.e.: motor vehicle or simply more passengers which gives flexibility
in varying the default configuration for which the calculations have been done.

The area of our wing is 1482.5 ft2, we calculated this number using the ratio (W/S)
from the matching chart, and using the taper ratio. According to our preliminary analysis, the
maximum thickness is calculated to be 1 foot in order to accommodate the calculated weight
of fuel. Using the weight of fuel we had from the preliminary weight analysis, to be 449.48
ft3are meant to fit this much fuel between the front and rear spar line of the wing.
Our thickness has been calculated to be 1ft and the root chord is 38.311 ft (t/c)r =
0.028. Also we have the tip chord is equal to 4.98 ft therefore our (t/c)t is equal to 0.11. We
determined our ∆CLTO of 0.21 and AR 2 and from appendix 15.7.2 we were able to deduce
our MCR. This gave us a MCR of 0.06.
CE 1.3.4 Identified issues and their solutions
1.3.4.1 Issues
There were some of the major problems or issues that we faced during the successful
execution of this project. The first and the foremost problem that I faced in this project was
the issue while comparing the weights of the components in aircrafts. This type of
comparison was important for making the project successful; however, the results were
coming erroneous. The second important challenge that I had faced in this particular project
was during the development of the stealthy configuration with the higher lift to drag ratio,
which is L/D ratio. This acceptable take off and the landing features should be absolutely
durable and efficient. However, the design made by me was not so strong and hence was
suffering from serious issues. Moreover, the airframe materials or structures of the design
were not at all advanced and thus it created major issues. All of these issues were to be
resolved on an immediate basis and proper solutions were to be found for the successful
execution of our project.
1.3.4.2 Solutions

I suggested some of the easiest solutions for all of these above mentioned issues and
hence our problems were solved. For the first issue, I suggested that we should change our
ideas and take readings of weight for the purpose of weight analysis. I myself took the
readings this time and was successful in doing proper weight analysis. I understood that the
take off weight should be around 75,000 pounds and the payload should be 6000 pounds for
the correct analysis. In my project, I tested with 5 crew members and the total weight of the
crew was 165 pounds. For the other issues such as lift to drag ratio or L/D ratio, I provided
the solution that this ratio should be calculated with lower lift to drag ratio. When this ratio
would be lower, the chances of failure would be lower and hence our problem was solved.
For the rest of the challenges in our project, I gave the suggestion to utilize effective and
durable engines and the proper integration of propulsion and airframe. To make the airframe
materials or structures advanced, I advised to increase our project funding to some extent and
I discussed with my project supervisor. Thus, I was successful in solving all the issues or
challenges in our project of supersonic business jet.
CE 1.3.5 Plan to produce creative and innovative work
Our plan was to produce creative as well as innovative work by means of segregating
all our works equally. We decided that each of us would execute our given responsibilities
with utmost sincerity and importance. We even decided to take proper follow ups of our
project for avoiding the delays and individual flaws. This type of plan helped us in making
our project of Supersonic business jet successful.
