Testing Being Conducted In The United Arab Emirates
The Sukhoi Superjet 100 flight prototype SN95005 landed at Ras
al-Khaimah (UAE) August 4th to undergo hot soak trails (above
+40C). The month-long test program includes extensive ground
testing of the engines, APUs, and avionics as well as check
flights. The aircraft is equipped with special detecting devices to
register the aircraft temperature in different zones.

Ground hot soak trials are aimed at proving the ability of the
aircraft, its systems and avionics to resist against temperature
shock. These tests are designed to confirm reliable APU and engine
start-up and operation at high outside air temperature even after
extended periods on the ground. In addition, the composite airframe
will be subjected to testing to demonstrate its heat tolerance.
Check flights are aimed at confirming stated takeoff and landing
performances as well as stable engines operation in steady and
variable modes of operation. The test program also includes the
performance of the continued takeoff, single-engine go-around, and
relight in flight.
