HELICOPTER AIRCREW UNDERWATER BREATHING DEVICE SRU-40/P

摘要

The Helicopter Aircrew Underwater Breathing Device, SRU-40/P is a compact , lightweight breathing assembly designed for emergency use by helicopter, E-2 and C-2 aircrew in the event of a crash landing in water (ditching). The SRU-40/P provides emergency breathing air upon demand to aid in a safe egress from a submerged aircraft. The device provides 1 to 3 minutes of breathing air depending upon the depth underwater, water temperature, and the individual using the device. The SRU-40/P is commonly known as the Helicopter Emergency Egress Device (HEED). This device is designed to be carried on the SV-2, AISAP, and AIRSA VE survival vests. A general illustration of the SRU-40/P mounted on a SV-2 is provided in Figure 1.rnThe SRU-40/P will be replacing a similar device, the SRU-36/P, which has been operational in the USN since September 1986 and was the first such system introduced into the Navy helicopter community.
