Using lightweight materials has the greatest potential for reducing jet engine weight. Ceramic alloys used in the turbine blades of the LEAP engine demonstrate how lightweight materials can operate in high pressure areas as research progresses. Future nanotechnology may allow even lighter, more durable materials. Lightweight materials provide the most effective weight reduction overall, saving costs through lower fuel usage long-term.
Modern aerospace industry is highly progressive and polymer composite materials have a positive and significant impact on it. At least 30-40 percent of modern airframes are now made of these composites, and this percentage is increasing rapidly due to technological advances in this field. Fiber-reinforced polymer composite materials are fast gaining ground as preferred materials for construction of aircrafts and space crafts. This review paper demonstrates brief about the components of polymer composites, its properties and its uses in aerospace industries. Polymer composites are highly efficient and environment friendly. Traditional materials are susceptible to fatigue and corrosion when composite materials provide resistance to both of this along with its significant amount of weight reduction. Due to high strength and stiffness of its fiber, polymer composite provides high “strength to weight” & “stiffness to weight” ratios. Apart from this, they possess good shear properties and low density .As a result, new generation aerospace engineers and aircraft designers are turning to polymer composite materials to make their flying vehicle and aircraft lighter, stronger and of course more fuel efficient. A brief introduction of composites usage in aerospace sector is given first. The nature of Polymer composite materials and special problems in designing and working with them are then highlighted. The advantages and disadvantages of polymer composites in aviation sector is discussed.

A Review: Aeronautical Components and Systems Should have their Weight Reduce...IJAEMSJORNAL
Lightweight requires cutting-edge materials and imaginative engineering to achieve the same or better technical performance with less material. This approach has been widely used in automobiles, fashion, and packaging, and the aviation sector may benefit from it. Traditional lightweight methods have used high-performance materials like composites, structural optimization using computationally-aided engineering, and cutting-edge manufacturing processes including additive manufacturing, foam metals, and hot forming. This article will examine the most prevalent lightweight technologies and their possible usage in aviation, such as power plants and airframe components. Solar-powered aircraft wings require improvement and are open to lightweight technology. High aspect ratios cause non-linear distortion, aileron reversal, flutter, and rigid-elastic coupling. Lightweight aircraft, UAVs, and rocket subsystems are all being considered. Cutting-edge optimization methods may optimize structural elements and geometrical parameters for optimum structural stiffness, least mass, and energy storage. Additive manufacturing may create composite or multi-material components that can serve several purposes.

1. JET ENGINE WEIGHT OPTIMISATION TECHNIQUES
USED IN INDUSTRY
Take home message:
Using lightweight materials has the greatest potential in reducing the weight of a
jet engine, key reasons and ideas are:
• The LEAP engine which uses ceramic alloys in the turbine blades is an example
of how lightweight materials are being used in areas of highest pressure. This
shows that with progressing research, the use of lightweight materials becomes
less restricted.
• Future Nano-technology could allow materials to be more durable and lighter.
• Lightweight materials as a whole reduce weight most effectively and thus are
more cost effective in the long term.
Why is an engine’s weight important?
An aeroplane’s jet engine can hold significant weight, particularly as jet engines are increasing in size
and mass. Engineers are developing different techniques to reduce the weight of a jet engine, this
would allow money to be saved on fuel and thus increase the likelihood of airlines purchasing the
engine.
Technique 2:
Lightweight
Materials
Technique 1:
Engine
Design
Reducing parts:
Fewer components would mean
less weight. Engineers aim to
ensure there is no ‘dead’ weight
in the engine and that minimal
components/stages are used.
An example of this is in the Rolls
Royce Advance Prototype which
has fewer stages in the
compressor.
Limitations of using lightweight
materials:
• Restricted use in the engine.
Lightweight materials cannot survive
extreme forces in compressors and high
temperatures in the turbine.
Benefits of Lightweight materials:
• Although expensive to manufacture, its
effectiveness in reducing engine weight
can save money on fuel in the long
term.
• Research into lightweight materials is
common among many industries and so
there are always new innovations.
Limitations of Engine design:
• The use of material cut-outs are very
restricted, since very low stresses are
mainly situated in the root of a blade
where centrifugal forces are minimal.
• Reducing the parts of a jet engine is also
restricted since aeroplanes are getting
larger, this could have an effect on the
thrust and efficiency of a jet engine.
Turbofan engines:
Some of many example of lightweight materials
being used in jet engines is the Rolls Royce Advance
engine, the GEnx engine and the CFM International
LEAP engine. Most models use Carbon fibre
materials for the main body of the fan blade, while
the LEAP engine also uses an innovative ceramic
matrix composites in the turbine. Although jet
engines are getting increasingly heavier, these
methods reduce the most amount of weight. For
example, the Rolls Royce advance is forecasted to
being 750lb lighter due to its Carbon fibre material.
Material Cut-outs:
This weight
optimisation technique
researched by Altair
engineering involves
cutting out material in
blades in regions of low
stress without
endangering the
structural integrity of
the blade. This is said
to achieve a maximum
of only 10% weight
reduction.
