Stainless steel welded shut eyebolt on the bulkhead at top of the airframe; Swivel link on the bottom of the main parachute

42
Q

What is the function of Shock Cord 2?

A

Takes the load on the inflation of the main parachute.

43
Q

What material is the nosecone made of?

A

Fibreglass 8 layers 290 GSM

44
Q

What material is the coupler made of?

A

8 layers 290 GSM

45
Q

How is the coupler attached to the nosecone?

A

8 layers 290 GSM fibreglass

51
Q

How is the boat tail attached to the booster tube?

A

Epoxied with HPR 25, 40 mm inside the booster tube. 4 layers of 290 GSM over the join 50 mm either side. (Same as nose cone)

52
Q

What material are the fins made of?

A

3 mm thick CF prepreg twill SE75.

53

What are the internal fin fillets made of?

A

ADR270 6 g each

56
Q

What are the external fin fillets made of?

A

HPR 25 12mm radius. Shaped on ends

57
Q

How was the fin tip-to-tip layup done?

A

12 layers of 200 GSM prepreg unidirectional.
Tailored laminate for strength in primary bending directions.
Symmetric about fin midline but not balanced.

58
Q

How is the fin slots machined?
