The Aeronautical Development Agency (ADA) has officially commenced the development of the Twin Engine Deck Based Fighter (TEDBF) cockpit mockup shell, as outlined in a detailed plan under Annexure-A. This initiative marks a significant step in the design and evaluation process for the TEDBF, a critical project aimed at enhancing India’s naval aviation capabilities.
The TEDBF cockpit mockup shell, equipped with mounting chassis, wheels, and jacks, will be developed in three distinct stages, with parallel design work to streamline the process. ADA will provide the 3D model of the shell in .igs/.stp format to the selected vendor post-NDA signing, after which the vendor will prepare fabrication drawings in coordination with ADA.
Development Stages
The project is divided into two main stages with specific objectives:
Stage 1: Finalizing Primary Controls (T0 + 3 Months = T1)
This stage focuses on establishing the foundational cockpit controls and their orientation. Key activities include:
- Positioning the front pressure bulkhead with windscreen rear arch.
- Incorporating cockpit floor with inclination adjustment provisions.
- Attaching the seat in the inclined bulkhead.
- Installing canopy longerons on both the left-hand (LH) and right-hand (RH) sides.
- Adding rudder pedal adjustment provisions in the X direction.
- Setting up Throttle Quadrant Assembly (TQA) adjustment provisions in the X and Z directions.
- Developing the Main Instrument Panel (MIP) structure with angular and positional adjustments.
- Creating 3D-printed models of the side control stick and throttle with adjustment provisions in the X, Y, and Z directions, including rotation about the Z-axis.
- Implementing a simplified rudder pedal model with X and Z movement provisions on the rudder pedal floor.
All components in Stage 1 will be powder-coated, with painting details to be provided during execution. Fabrication tolerances will adhere to ADA’s documentation.
Stage 2: Finalizing Secondary Cockpit Controls (T1 + 2 Months = T2)
The second stage focuses on refining the cockpit controls and their grouping:
- Developing a 3D-printed Head-Up Display (HUD) model with an adjustable HUD mounting bracket.
- Creating 3D-printed models of the Large Area Display (LAD), Backup Display Unit (BDU), and two 5×5 Secondary Display Units (SSDUs).
- Positioning LH and RH console panels with side covers, including angular adjustment provisions in the Z direction.
- Adding switch labels with velcro/glue provisioning for identification, selection, and grouping of controls, prioritized for finalizing switches and indicators in the LH and RH consoles.
- Positioning the center console.
Stage 2 components will be integrated with those from Stage 1, ensuring a cohesive assembly. As with Stage 1, powder coating and adherence to ADA’s fabrication tolerances are mandatory.
Delivery Schedule
The project timeline is structured as follows:
- Stage 1: T0 + 3 months (T1).
- Stage 2: T1 + 2 months (T2).
- T0: The date of model release after purchase order (PO) placement.
The vendor is required to demonstrate compliance with the inspection document provided by ADA, using relevant tools to ensure tolerance requirements are met.
