2.  Introduction
 History of Aviation Industry
 Principle of working
 Concepts
 Advantages
 Disadvantages
 conclusion

3.  The first aircraft to fly supersonically in level
flight was the American Bell X-1 experimental
plane which was powered by a 6000-lb thrust
rocket powered by liquid oxygen and ethyl
alcohol.

4.  History of aviation started with Kites
 Super sonic and Hyper sonic flights were
Introduced
 (which is too heavier than airjets-
unscientific design)

5.  17th 18th 19th century Hydrogen Gas is
discovered which leads to the invention of
Hydrogen balloons.
 Physicist- leads to the H-balloons with hot air
 20th century- Aerodynamics made by
physicist.

6. SUPER SONIC AIR CRAFT PRINCIPLE:
 Flight at speeds greater than that of sound are
supersonic.
 The range of speeds from Mach number 0.8 to 1.2
is known as transonic

9.  Large range of concepts requiring flexible, high-
fidelity geometry representation
 High sensitivity to geometric changes
 Many sources of non-smooth behavior
 High dimensionality search space

10.  Multidisciplinary Analysis and Design Methods
 Parametric Geometry
 Viscous and Inviscid Analysis Tools
 Suite of Search Methods
 Multiobjective / Multipoint Optimization
 Multifidelity Search
 Experiments

Boom tailoring
Wing/body/nacelle design
with transition and total
drag estimation

12.  High Speed
 Quick Service
 Easy Access:
 No Physical Barrier:
 Natural Route:
 National Defence:
 No Infrastructure Investment

13.  Risky:
 Very Costly:
 Small Carrying Capacity:
 Unreliable:
 Huge Investment
