Skirt

Benefits and technical summary

Airflow sweeping under the body of the trailer increases the vehicle drag due to chaotic turbulence and pressure drag on the under-body structures, including the wheels and the axles. This under-body drag increases considerably with crosswind effects. Trailer skirts minimize the under-body drag by covering these structures from the forward airflow and crosswinds.

 

Based on UK wind statistics, the corresponding wind-averaged drag reductions due to the trailer skirts are estimated at 4 - 6%. An average 40 tonne articulated lorry, driving 70,000 miles a year, would save £2,400* every year if a 5% fuel saving was achieved.

 

Independent fuel trials conducted by MIRA showed the following results:

 

2.9% average fuel saving when driving at 56 mph

2.4% average fuel saving when driving at 40 mph

1.1% average fuel saving when driving at 30 mph

 

With these results an Aerotails side skirt could pay for itself after only 9 months of use.
