Abstract
There is provided an arming apparatus for a store, the apparatus comprising: a first attachment system and a second attachment system; a linking connector coupled with the first attachment system and the second attachment system; and an arming connector coupled with the linking connector and a first fuze input of the store; wherein each of the first attachment system and the second attachment system comprises: an arming unit; a first frangible connector coupled with the arming unit and the linking connector; and a second frangible connector coupled with the linking connector and the store.
Claims15
1:
- An arming apparatus (200) for a store (204), the apparatus comprising:
- a first attachment system (202a) and a second attachment system (202b);
- a linking connector (208) coupled with the first attachment system (202a) and the second attachment system (202b);
- and
- an arming connector (210) coupled with the linking connector (208) and a first fuze input (214) of the store (204);
- wherein each of the first attachment system (202a) and the second attachment system (202b) comprises:
- an arming unit (220);
- a first frangible connector (224) coupled with the arming unit (220) and the linking connector (208);
- and

2:
- The apparatus (200) according to claim 1, comprising a gag rod wire (232) coupled with the store (204) and a second fuze input (234) via the second attachment system (202b).
3:
- The apparatus (200) according to claim 1, wherein each attachment system (202a, 202b) comprises a safety connector (228a, 228b) coupled with the linking connector (208) and the store (204).
4:
- The apparatus (200) according to claim 3, wherein the length of the safety connector (228a, 228b) is longer than the length of the arming connector (210).
5:
- The apparatus (200) according to claim 1, wherein the linking connector (208) comprises a first ring and a second ring, the linking connector (208) being coupled with the first attachment system (202a) via the first ring and with the second attachment system (202b) via the second ring.
6:
- The apparatus (200) according to claim 1, wherein one or more of the first frangible connector (224a, 224b) and the second frangible connector (226a, 226b) comprises a shear wire.
7:
- The apparatus (200) according to claim 1, wherein the first frangible connector (224a, 224b) has a higher breaking force compared with the breaking force of the second frangible connector (226a, 226b).
8:
- The apparatus (200) according to claim 7, wherein the first frangible connector (224a, 224b) has breaking force of between approximately 700 N and 1000 N.
9:
- The apparatus (200) according to claim 7, wherein the second frangible connector (226a, 226b) has a breaking force of between approximately 100 N and 200 N.
10:
- The apparatus (200) according to claim 1, wherein the arming unit (220a, 220b) of each of the first attachment system (202a) and the second attachment system (202b) comprises an arming solenoid, wherein the arming solenoid has a first attachment force for the first frangible connector (224a, 224b) when the arming unit is energised and a second attachment force for the first frangible connector (224a, 224b) when the arming unit solenoid is unenergised.
11:
- The apparatus (200) according to claim 10, wherein the second attachment force is greater than a breaking force of the first frangible connector (224a, 224b).
12:
- The apparatus (200) according to claim 11, wherein the first attachment force is lower than a breaking force of the second frangible connector (226a, 226b).
13:
- The apparatus (200) according to claim 11, wherein upon activation of an ejector release unit and wherein the arming units are energised, the second frangible connector (226a, 226b) of the first and second attachment systems (202a, 202b) are configured to break under the weight of the store (204), such that the load from the store is transferred to the ejector release unit via the arming connector (210) thereby activating the first input (214) of the fuze system (216).
14:
- The apparatus (200) according to claim 13, wherein the first frangible connector (224a, 224b) of the first and second attachment systems (202a, 202b) is configured to break following activation of the first input (214) of the fuze system (216) due to the weight of the store (204).
15:
- A method of operating the arming apparatus (200) according to claim 1, the method comprising:
- energising the first arming unit and the second arming unit;
- and
- releasing the store from hooks of an ejector release unit.
