Wingtip vortices

A wing generates aerodynamic lift by creating a region of lower air pressure above it. Fluids are forced to flow from high to low pressure and the air below the wing tends to migrate toward the top of the wing via the wingtips. The air does not escape around the leading edge of the wing due to airspeed, but it can flow around the tip. Consequently, air flows from below the wing and out around the tip to the top of the wing in a circular fashion. This leakage will raise the pressure on top of the wing and reduce the lift that the wing can generate. It also produces an emergent flow pattern with low pressure in the centre surrounded by fast-moving air with curved streamlines.

Wingtip vortices only affect the portion of the wing closest to the tip. Thus, the longer the wing, the smaller the affected fraction of it will be. As well, the shorter the chord of the wing, the less opportunity air will have to form vortices. This means that for an aircraft to be most efficient, it should have a very high aspect ratio. This is evident in the design of gliders. It is also evident in long-range airliners, where fuel efficiency is of critical importance. However, increasing the wingspan reduces the manoeuvrability of the aircraft, which is why combat and aerobatic planes usually feature short, stubby wings despite the efficiency losses.

Another method of reducing fuel consumption is the use of winglets, as seen on some modern airliners such as the Airbus A340. Winglets work by forcing the vortex to move to the very tip of the wing and allowing the entire span to produce lift, thereby effectively increasing the aspect ratio of the wing. Winglets also change the pattern of vortices in the core of the vortex pattern, spreading it out and reducing the kinetic energy in the circular air flow, which reduces the amount of fuel expended to perform work by the wing upon the spinning air. Winglets can yield worthwhile economy improvements on long-distance flights.

Busy few days for Coast Guard with Medivac to London

 

The Irish Coast Guard successfully assisted the HSE with the medical evacuation of a young transplant patient from Dublin to London yesterday.

The request for assistance was received by the Coast Guard at 2am yesterday morning and involved a very critical timeframe. Within ten minutes, the Dublin-based Coast Guard helicopter crew were assembled, briefed and shortly afterwards, Rescue 116 and crew were en-route to Heathrow airport in London with the young patient, who was later transferred to Kings Cross Hospital.

At 11am on Thursday, Dublin Coast Guard co-ordinated the rescue by the RNLI of 6 children and an adult from overturned canoes off Clogherhead.

At 17:52pm Thursday evening, the Castletown Coast Guard Unit were tasked to respond to a call of an injured person on rocks at Ballydongen Beach, Allihies, Co. Cork.
At 7:56am Friday morning, the Shannon-based Coast Guard helicopter Rescue 115 evacuated an ill crewmember from a fishing vessel 105 miles west of Loop Head with the Sligo Coast Guard Helicopter Rescue 118 standing by as top cover for the long distance operation.

Speaking yesterday, Director of the Irish Coast Guard Chris Reynolds said: “It might seem like a busy 48 hours for the Coast Guard – but this is nothing out of the ordinary for our teams, who operate on a 24/7 basis and are always on standby in the event of emergencies. I would like to congratulate all of our teams who were involved in the successful medical evacuations that took place in the 48 hours. In particular, the evacuation at very short notice of the young transplant patient yesterday morning. It is very unusual for the Coast Guard to operate out as far east as London, but we are delighted that the transfer went smoothly and that we could help.“
