Executive Summary

Rejuvenation of the

Department of Aerospace Engineering.

Brief for discussions

with

Mr. Subhash Tantry


July 2001



Faculty of the Department have brainstormed
and have evolved a
student
-
centric

vision. Quality education & quality research go hand in hand. We believe that a
strong educational programme and infrastructure aimed at overall development of the
student is the primary requirement. This shall offer

the best foundation to build
research activities on. First round of efforts are targeted towards realising this.
(Phase
-
1). It is expected that 2 years will be required to implement Phase
-
1.



Focus in education has shifted from strong pedagogy to s
elf
-
learning. But
department has not been able to provide students with opportunities for exploration
and self
-
learning. A
Student Activity
-
cum
-
Creativity Centre

is a pressing need.




Teaching labs, which were state of the art 3 decades ago, are inadequa
tely equipped
as of now. Formal education through pre
-
planned laboratory experiments do play
an important role in shaping the minds of students. There is urgency in the need to

Rejuvenate the teaching laboratories
.



Research Scholars, students and Facul
ty have always been involved in research for
years but have suffered greatly from inability to travel and interact with fellow
researchers. Few
fellowships

to enable this exchange will be of immense value.



Present laboratory staff of the Department has be
come unable to provide quality
support in the electronics & computer intensive environment
. Special staff
positions

(2 as of now) are recommended to provide support to planned activities.
These positions will be contract positions for a period of 5 year
s.



The need for an
overall facelift

of the Department to provide a workplace
environment commensurate with the quest for quality education & research is felt
.

Phase
-
1 funding is prioritized into two levels to facilitate execution of the plan
depending fun
ding availability. Level
-
1 requirements are of the order of US$ 750,000,
which includes US$ 320,00 in endowment.

Vision of

The Department of Aerospace Engineering

Phase


I : Modernisation

Brief for discussions with Mr. Subhash Tantry

July 2001



THE

BACKGROUND


The Department of Aerospace Engineering at IIT Bombay has been in the
forefront
of
Aerospace Engineering education & research relevant to national projects. It has grown
from an Aeronautical design
-
based education centre at start
-
up, to an up
coming centre
of excellence in classroom teaching of core & critical technologies in Aerospace
Engineering. Several state
-
of
-
the
-
art research activities have flourished in the
Department and provided valuable inputs to national aerospace programmes. Fund
ing
for specific research topics has not been a major problem especially over the last
decade, but the research has always been directed by the end
-
user. Funding of a
generic nature for overall balanced growth has always been a major challenge.

Computat
ional expertise is the hallmark of the Department, while the deliverables from
experimental facilities have lagged far behind because the laboratories still possess
outdated equipments that need immediate upgradation or replacement. Undergraduate
training

in these laboratories now seems primordial.


THE MOTIVATION

Having identified these problem areas, the Department faculty have brainstormed &
identified several activities where funding should be allocated on priority, for balancing
the high
-
end computa
tion based research & classroom teaching standards, with state of
the art laboratory education, high
-
tech working environment, and a pleasing ambience.

The notes that follow present the short term, immediately realizable and tangible goals,
termed as
Ph
ase
-
I
. The Department is also in the process of identifying research areas
in critical technologies in Aerospace Engineering, which will lead to a much stronger
impact internationally than research in conventional core areas, termed as
Phase
-
II
.
These cr
itical areas are a major component of the long
-
term goals of the Department.


THE SCOPE (PHASE
-
I)

The Department now needs to address short
-
term goals on a priority basis. Hence, the
first round of funding is sought towards this, and is aimed at raisin
g the level of
infrastructure for teaching and to prepare the Department to take up world
-
class
research.

Activity
-
cum
-
Creativity Centre

To begin with, these notes discuss the creation of a new Departmental Activity
(Creativity) Centre, to promote studen
t non
-
academic curiosity & activities in
Aerospace Engineering. This centre will also serve to popularize Aerospace
Engineering within the campus, and enhance the standing of the discipline in the

4

country in the long run. Students have often expressed th
e need for a facility that will
allow them to freely explore their innovative ideas. They had expressed this directly to
Mr. Tantry during his visit to the Department. During the past 6 months, the
Department deployed in
-
house funds and assessed the usef
ulness of such a facility. The
results are extremely encouraging. The visibility of this centre will depend on the level
of funding, i.e., either an activity housed within the existing building space, or a
separate building designed exclusively for the a
ctivity.

The Centre will encourage students to participate in design (and other similar)
competitions, and to organise competitions in aerospace area. The centre will interact
with engineering colleges in and around Mumbai through lecture
-
demonstration
of the
projects enabled by the Centre. The centre will host students from other IITs and
engineering colleges to spend summer to work on projects. An expert committee will
see how deeply the student has thought about his idea, before giving access to fac
ilities.
Access will be available to all students of the campus as long as the idea to be
investigated is Aerospace in nature. Appendix
-
I is a detailed proposal for setting up an
Activity
-
cum
-
Creativity Centre.



Special Staff Positions

Technical staffs

whose skills are consistent with the present day electronics &
computer
-
driven environment are difficult to find in an academic environment
surrounded by a comfortable job market for their skills. Very rarely, do people with
such skills turn to education
al Institutions for employment. A few who show such
inclinations are discouraged by the poor remuneration package from conventional
project funding. Hence, these notes include two staff positions; in order to offer
substantial support to planned activiti
es (Appendix
-
II). It should be noted that
provision is made here for a 5
-
year contract appointment.

Augmentation of Laboratories

The new proposed centre can be sustained only if other basic infrastructure is upgraded.
Hence, the augmentation of teachi
ng laboratories is then elaborated in the various
Appendices (III to V), as augmentation of teaching laboratory facilities & research
projects of undergraduates & postgraduates. The present facilities were established
more than three decades ago. There i
s an immediate need to inject state
-
of
-
the
-
art
equipment into these laboratories. Other funding agencies are unlikely to support this
move.

Conference Travel Grant

This is followed by travel requirements for widening the research exposure of faculty
an
d students, since it has become progressively difficult for researchers (Faculty,
research scholars & students) to travel and interact with fellow researchers from within
and outside the country. This is expected to give a significant boost to the researc
h
image of the department, and is an attempt to excite the undergraduate students towards
research. Appendix
-
VI is a proposal towards this goal.

Department Facelift

The need for an overall facelift of the Department building that is heading towards
qua
lity teaching & research has been strongly felt especially with an exponential
increase in the number of national and international distinguished visitors. Further,

5

several basic logistics are either missing or inadequate. These range from appealing
clas
sroom furnishing to faculty furniture.

The above proposed
Activity
-
cum
-
Creativity Centre, Chair Professorships, special
staff positions, and travel grants can be suitably named
.


IITZeus


An Example of Development Activity

Department has in the past e
xcelled in several development activities. IITZeus
(http://
www.aero.iitb.ac.in/~iitzeus
) is a classic example of research in the area of grid
generation finding expression through the development of a pac
kage. IITZeus has
captured the attention of the scientific community in the area of computational
mechanics, within and outside the country. It is believed that IITZeus has a strong
potential for commercialization. A strong R&D team to back future grow
th of these
package is available within the department. Students and research staff who have
contributed to the development effort have shown keenness in setting up a support cell.
Some funding in the nature of "Angel VC" and advice from people who are
experienced in commercialising software is sought. Several other efforts in software
development will be encouraged if IITZeus makes an impact. A separate document
describing IITZeus will be made available.


Research Focus for Phase
-
II

Faculty is curr
ently engaged in research activities with funding from a variety of
agencies. National Aerospace programmes, which are denied technology in the global
market, have relied heavily on educational institutions for support. Several of the
funded activities

in the department have been to provide research & development inputs
to national aerospace programmes

Research thrust in Phase
-
II needs to be a careful strategy to sustain support to national
effort, while striving for global visibility in research. F
aculty is deeply involved in
arriving at this strategy. A group of faculty members are looking into this.

Department will put together research proposals for Phase
-
II, indicating goals, strategy
to realise the goals and metrics to assess success. Propos
als will also identify experts in
the area, from within the country and outside, who can help in assessing the proposal
and also the progress.

Creativity Centre


Students passing through IIT campus are a repository of innovative ideas and creative
thoughts. Formal education and pre
-
planned laboratory experiments do play
an
important role in shaping the minds of these students. Nevertheless, it is essential to
prompt students to dream and then give shape to the dreams. Facilities that will enable
students to experiment are essential. Lack of infrastructural support in t
erms of work
place, equipment etc. has in the past killed the enthusiasm of such students at an early
stage. A facility where students can work on technical problems of their interest, but
which has no academic credits attached to it is urgently required.

This will also expose
students to efforts involved in product development.


During the past months, an attempt has been made to see if students are likely to utilise
such facilities, if created. The department and Centre for Aerospace Systems Design &
E
ngineering (CASDE) made available infrastructure and funds in a small way.
Students have exploited this to do short
-
term projects, which were successfully
completed. Two of these are,



1.

Use of GPS for Navigation: This work was done by 2nd year B.Tech. s
tudents and
involved implementing the interface between commercial, handheld GPS and a
laptop. Students had to read literature and have a good understanding of GPS.
They could map some of the routes within the campus as they traveled in a car.



2.

Devel
opment of Inertial Navigation System (INS). This
project is an ongoing summer project and is undertaken by
2
nd

year BTech students. Commercially available sensors
from game market are used in this project. Project aims at
a product that can be used to d
emonstrate basic principles
of INS. Once completed, students can carry the INS
package around within the premises of a lab; unload the
data to a PC and re
-
create the path.



8

Several students, who wanted to try out their ideas by making and flying models,
used
the facility for aeromodeling. During last summer 7 aerospace engineering students, 3
from Park Engineering College, Coimbatore and one from IIT Kharagpur spent time at
this facility and benefited immensely. Students of Department of Aerospace
Engi
neering are eagerly awaiting augmentation of such facilities.



Major inventory of such a facility in the future will be electronics components
including microprocessors, microcontrollers, sensors, actuators, etc. Construction
material and facilities will

be available. Discussion group will be formed for exchange
of ideas. Special encouragement will be given to students who enlist in design
competitions. Centre will also encourage innovation in B.Tech & M. Tech thesis.



A list of items that will be in

the inventory of the Centre and funds required for the
same; along with fund requirement on other items are indicated in the Table.


The Centre will encourage students to participate in design (and other similar)
competitions, and to organise competitions

in aerospace area. Centre will interact with
engineering colleges in and around Mumbai through lecture
-
demonstration of the
projects enabled by the Centre. Centre will host 4 students from other IITs and
engineering colleges to spend summer to work on
projects.


An expert committee will see how deeply the student has thought about his idea, before
giving access to facilities. Access will be available to all students of the campus as
long as the idea to be investigated is Aerospace in nature.


Centre wi
ll start functioning without much delay from within the department premises.
In the meantime, a strategic location for the new premises in close proximity to the
department will be found and a design for the premises will be evolved; all with close
consult
ations with Mr. Subhash Tantry.
