1. Title of the invention

Non operational launcher for Carriage of Typical CCM for Fighter & Trainer Aircraft

2. Field of invention

It is a mechanical engineering design used in supersonic military aircrafts for carriage of non-operational missiles in place of original operational launchers.

3. Use of invention

This invented adapter finds its applicability in the military (fighter/trainer) aircraft for the carriage of dummy typical CCM for Operational Clean Configuration (OCC).

4. Prior art

Current practices are to use operational launchers to carry dummy missiles for the fighter/trainer aircrafts to meet the Operational Clean configuration (OCC) requirements. The usage of operational launchers and missiles require costly inventory, maintenance and service.

5. Draw backs of prior art

1) Operational Launchers are short in supply and costly.

2) Operational launchers have to be regularly serviced and maintained for being flight-worthy.

3) Skilled man power and ground support logistics are required for maintaining operational launchers, flight worthy.

6. Comparison between prior art and present invention

The present invention is made to reduce the above mentioned drawbacks of the current scenario in Light Combat Aircraft.

7. Aim of the invention

Aim of the invention is to reduce the overheads for maintaining operational launchers. This will also create self dependency for the aircraft operation.

8. Summary of the present invention

The non-operational launcher for dummy typical CCM is aerodynamically designed aluminum machined housing capable of operational speed of 1.6 mach. This will exactly simulate weight, C.G & M.I (centre of gravity & moment of inertia) properties of the operational launcher for the entire range of aircraft operational envelope. Necessary interface provisions are provided in the non-operational launcher for integrating the dummy typical CCM.

Fig-3 shows the details of forward attachment of missile to launcher with locking mechanism.

Fig-4 shows the details of middle attachment of missile to launcher.

Fig-5 shows the details of rear attachment of missile to launcher.

10. Statement of invention

This invention facilitates the operational agency to perform aircraft sorties in the OCC (operational clean configuration) without depending on the operational launchers. Since the non-operational launcher is designed indigenously, maintenance requirement and cost are minimum.

11. Detailed description of invention

The non-operational launcher for dummy Typical CCM is aerodynamically designed high strength aluminum alloy machined housing capable of operational speed of 1.6 mach. This will exactly simulate weight, shape, C.G & M.I (centre of gravity & moment of inertia) properties of the operational launcher for the entire range of aircraft operational envelope.

The attachment points, weight, C.G and M.I are maintained as per the original launcher so as to enable the user to integrate the dummy Typical CCM without any modification/ alteration.

The interface between missile and non-operational launcher is done with three missile attachment brackets at forward, middle and rear locations. The locking of missile is ensured with a blind bracket at rear attachment bracket and a stopper at the forward attachment bracket. When secured, the stopper makes a face-to-face butting with the top flange of forward attachment bracket.

The non-operational launcher is properly coated to comply with environmental protection standards as per MIL-STD-810B.

The non-operational launcher consists of (Refer fig-1) Launcher housing (1), Missile attachment bracket (fwd.) (2), Missile attachment bracket (mid.) (3), Missile attachment bracket (aft.) (4), Stopper (5), End cap (6).

Claims

1. Operational launchers are replaced with non-operational launchers to make the fighter/trainer aircrafts meet the operational clean configuration (OCC) requirements and make the fighter/ trainer aircrafts flight-worthy for regular sorties.

2. The non-operational launchers are designed indigenously, with minimal maintenance requirements and costs.

3. The non-operational launchers are aerodynamically designed to take loads at an operational speed of 1.6 mach.

4. The non-operational launchers use a positive locking mechanism so that the dummy typical CCM remain intact with the fighter/trainer aircrafts during the sorties.

5. This invention saves our Foreign exchange reserve.
