Helicopter instructor experiences an near midair collision with a twin turboprop on final approach. The helicopter was on a steep approach and making position reports; while the king air was on the straight in ILS and apparently not making position reports. The twin turboprop pilot detected the helicopter and went around to the right side.

Narrative:
During a training flight the helicopter was flying right traffic patterns for runway xy. The [helicopter] was completing a steep approach to the aiming point markings of runway xy when a twin turboprop passed off the right side of the runway executing a go around. Radio calls were made on all legs of the pattern by the [instructor]. Both instructor and student do not recall hearing any transmissions from the twin turboprop. It was noted that com 1 in the helicopter was not functioning. This occurrence was used as a teachable moment for equipment cross check; situational awareness and collision avoidance. A safety meeting was held to discuss the event and collaborate with other pilots. A NOTAM was issued to change the flow of helicopter traffic.
