1. Title of the invention
Sliding Battery Tray for fighter aircraft.

2. Field of invention
It is a mechanical engineering design used for aircraft battery installation.

3. Use of invention
This invented Sliding Battery Tray finds its applicability in any type of aircrafts that uses cube shaped battery.

4. Prior art
In previous arrangement Battery Tray mounted on the Battery bay floor by means of 4 bolts and then battery was lifted into the tray and secured by means of four holders ,Two Top Rods (For guiding the position of the holders) and two channel assemblies.

5. Draw backs of prior art
The lifting of battery in to the tray and removal was very cumbersome because of its weight. Securing of battery involved tightening of four nuts (two in front and two in back) by assembling four holders, Two Top Rods (For maintaining the position of the holders) and two channel assemblies. Assessing two back nuts was very difficult due to space constraint in the battery bay.

To install or remove the battery from aircraft was taking more time because more parts required being assembled/dissembled each time when battery is installed /removed from the aircraft.

6. Comparison between prior art and present invention
In the present design. Battery and tray are assembled on bench and the assembly is installed in to the aircraft by sliding on the rails provided in the battery bay floor. Here battery is installed by tightening four bolts in front and in back by engaging spigot of tray with socket bracket on the Battery bay floor. In present design assembling of battery in to battery tray, securing it by means of holder, nut etc is done on bench, thereby reducing work on aircraft. This in turn reduces aircraft on ground (AOG) time. With this design, battery tray assembly can be lifted by means of loading trolley and then slide on to the rail in the battery bay, thereby eliminating the additional man power required to install the battery in the aircraft.

7. Aim of the invention
Aim of the invention is to eliminate the draw backs in the present practices / components and also reduce aircraft on ground (AOG) time and improve the maintainability of the aircraft.

8. Summary of the present invention
In Sliding Battery tray, Battery and tray are assembled on bench by placing the battery in to the tray and locking it by means of two holders and Nuts. This assembly is installed in to the aircraft by sliding it on the rails provided in the battery bay floor. Here battery is installed by tightening four bolts in front and in back by locking spigot on the tray with socket bracket on the Battery bay floor. In present design assembling of battery in to battery tray, securing it by means of holder, nut etc can be done on bench thereby reducing work on aircraft. This in turn reduces aircraft on ground (AOG) time. With this design battery tray assembly can be lifted by means of loading trolley and slid in to the battery bay thereby eliminating the additional man power required to install the battery in the aircraft.

10. Statement of invention
With Sliding Battery tray Battery can be installed easily in to the aircraft compared to previous one. Complete assembly of the battery with tray is done on the bench, thereby reducing aircraft on ground (AOG) time. In this design battery tray assembly can be lifted by means of loading trolley and slid in to the battery bay thereby eliminating the additional man power required to install the battery in the aircraft.

11. Detailed description of invention
In Sliding Battery tray, Battery and tray are assembled on bench by placing the battery in to the tray and locking it by means of two holders and Nuts. This assembly is installed in to the aircraft by sliding it on the rails provided in the battery bay floor. Here battery is installed by tightening four bolts in front and in back side by locking spigot on the tray with socket bracket on the Battery bay floor. In present design assembling of battery in to battery tray, securing it by means of holder, nut etc can be done on bench thereby reducing work on aircraft. This in turn reduces aircraft on ground (AOG) time. With this design battery tray assembly can be lifted by means of loading trolley and slid in to the battery bay thereby eliminating the additional man power required to install the battery in the aircraft.

Claims

1. This invention replaces lot of parts used to secure battery with tray and assembling of battery in to tray, securing it by means of holder; nut etc is done on bench, thereby reducing work on aircraft. This in turn reduces aircraft on ground (A06) time. With this design, battery tray assembly can be lifted by means of loading trolley and then slide on to the rail in the battery bay, thereby eliminating the additional man power required to install the battery in the aircraft.

2. This invention addresses the draw backs in the present practices / components.

3. This invention improved the maintainability of the Aircraft.
