Conceptual Design
The early stages of design have the biggest impact on engine performance, environmental impact and economics. An integrated engine design model (IED) that provides support for multidiscipli-nary conceptual and preliminary design and includes uncertainty/risk analysis and economic mod-eling is what is developed these days . The group can assist you in the conceptual design in the areas of
- Constraint analysis
- Mission analysis
- Propulsion Requirement Analysis
- Cycle selections

Conponent Design & Detailed Design
IHL currently undertakes the design of all the components that are not in the hot flow path. These are for the various components like Fan/compressor, Combustion Chamber, Turbine LPT & HPT, Intake/nozzle Once proven the group makes detailed design (2d& 3D)using Catia, Pro-E etc
-------------------------------------------------------------------------------------------------------------------------
Matching of Components
Extensive experience in aero engine and aero derivatives in detailed 2D & 3d component design and detailing using unigraphics,Catia and Pro-E, proficiency in designing class-2 engineering changes, Weight /cost /manufacturability trade studies
-------------------------------------------------------------------------------------------------------------------------
Cycle analysis: parametric & off design performance analysis:
Performance and simulation analysis using In-house proprietary codes, engine test coverage, performance test data analysis of steady state and transient data, simulation of engine data, Prediction of engine behavior and field support
-----------------------------------------------------------------------------------------------------------------Go Top
Component Pro-type Manufacture & Testing
IHL with the support of HAL is in a position to carry out the prototype manufacture and testing of some of the components
-------------------------------------------------------------------------------------------------------------------------
Engine Layout:
IHL has the expertise to do the engine layout and look at interferences The group can do tolerance dimensioning and other related studies like layout design and component matching, clearance mapping, engine centreline control, mounts deisgn, engine air-aircraft interface design }
-------------------------------------------------------------------------------------------------------------------------
Structural Analysis
IHL can carry out finite element analysis 2D/3D FE Modeling – Meshing from CAD Models, Stress/Deflection Analysis linear and non-linear , Low Cycle Fatigue, rotor dynamics and engine loads, Thermo mechanical fatigue .
-------------------------------------------------------------------------------------------------------------------------
Rotor Dynamic analysis/vibration analysis:
Vibration Survey,Modal analysis,engine loads analysis, engine mounts and bearing lifing prediactions, bird strike and Fan blade –off analysis
-------------------------------------------------------------------------------------------------------------------------
LRU Design/matching
Design of oil & FUEL pumps (impeller design is a export control) , external wrap-up routing design and modal vibration analysis are some of the work done by the group. It can assist in the LRU design and manufacture
---------------------------------------------------------------------------------------------------------------Go Top
Air system design & Integration:
Airsystem conceptual & design design, solutions field support issues , flange and boss leakage anlysis and impact studies, Nacelle,ventilation and anti-ice system design, analysis and test support, development of SIMULINK model for sensitivity analysis.
-------------------------------------------------------------------------------------------------------------------------
Engine testing :
Development of testplans, ENGINE test coverage, Test analysis of steady state and transient DATA, ENGINE behavior and simulation modeling of test data and component matching & Cycle optimization studies
-------------------------------------------------------------------------------------------------------------------------
Redesign and analysis – iterations
As the product complexity grows, and diverse team can collaborate across the globe. Design evaluation and trade off studies form an important part of development, so that the design errors are handled in the early phase of the product lifecycle. IHL is capable to do high end analysis and optimization studies using the best of breed analysis software's
-------------------------------------------------------------------------------------------------------------------------
Certification :
Support for FAA report writing and test documentation & support for analytical validation for certification with class-2 engineering changes
