Defiance has extensive experience in concept definition and feasibility studies for the design and development of aerospace and spacecraft systems, sub-systems and components. These include space launch vehicle motors, a space re-entry vehicle, aircraft sub-systems and components for military and civil applications.
Defiance offers the following services to global aerospace customers in this space:
- Functional Requirements
- Feasibility Study
Defiance has expertise in developing a concept to a preliminary design stage including sizing of components and sub-systems, followed by detail design of parts and assemblies. Some of the applications of our design service include space launch vehicle motors, space re-entry vehicle, empennage of aircrafts, outer wing box for a commercial aircraft, fuselage sections of several aircrafts, and aircraft cargo doors.
Defiance has all the commercially available CAD, CAE, CFD and modelling tools widely used in the aerospace domain. The team also has a thorough understanding of the GD&T process and has experience in Model Based Definition. The two phases/stages in this service offering are given as follows.
- Preliminary Design
- Detailed Design
Design validation is a very important developmental activity in the aerospace component design and needs extensive documentation such as certification reports as per aviation authorities norms and regulations. With our vast knowledge and with manufacturing eco-system, we can take up the tasks of building the component, testing it and validating the design.
We have experience in undertaking the following activities as part of certification process.
- Product/Component Testing
- Certification Support
Defiance can take up the production support leveraging the manufacturing expertise and experience of our group companies. With access to a large vendor base, we have established a robust production process to meet the stringent international standards. We have a team of core designers who are adept in reverse engineering, value engineering, process optimization and lean manufacturing.
We have extensive experience in the design, development and production of Tooling and Fixtures as well as integrating them on the shop floor. We provide the following services:
- Tooling and Fixture Design
- Vendor evaluation
- Supply chain Management
- NC Programming
- Reverse Engineering
- Value Engineering
Life Cycle Management
At Defiance, we have a team well experienced in post design activities. This includes providing timely solutions, information to take decisions in salvaging, rejecting components or parts with dimensional deviations arising during manufacturing, repair, and wear and tear. We follow a robust process for carrying out engineering changes that occur during design and certification stages.
Our technical documentation team has good understanding of all the latest standards and requirements for this activity, and, they use a wide variety of tools for documentations and illustrations according to the requirements of their customers.
We also have a dedicated team for data migration from one platform to another as well as for creation of drawings and 3 D models from hard copies of drawings. We offer the following services:
- Repair and Concessions
- Engineering Changes
- Legacy Data Migration
- Technical Publications
We have capabilities in electrical, mechanical and embedded systems. In the electrical domain, we are primarily active in the design and simulation of aircraft electrical wiring installations, which involves the modelling of various connectors, cable systems and piping systems for various aircrafts. We have an experienced team in the design of electrical wiring harness installations serving major customers in this domain of activity.
We also have a core team of engineers engaged in activities ranging from specification development to testing of software for embedded systems in communications, navigation, engine control, display management, etc. We offer the following services:
- Embedded Systems and Software
- Mechanical Systems
- Electrical Wiring Harness & Installations
Defiance has developed a team dedicated for Intellectual Property creation that is working on several advanced topics such as new technologies using MEMS pertaining to structural health monitoring, systems for noise and vibration control and Green composites. In addition, we have a team experienced in structural integrity and life extension of aircraft structures.
