NoseCone Benefits


NoseCone smoothes airflow over the whole pan reducing turbulence and drag at sides and rear. Turbulence that gets drag along increases the volume of the body and affects the stability. Streamlining the front reduces drag and turbulence, saves fuel and increases the stability. Better stability has also been shown to assist in longer tyre life and greater safety through reduced driver fatigue.

NoseCone Benefits Summary

  • Guaranteed fuel saving
  • Greater stability
  • Maintenance free
  • Increased speed or fuel savings
  • Less buffeting from other trucks
NoseCone is the largest selling deflector on the Australian market with over 40,000 units in service since 1981 and refined over 20 years for Australian conditions and configurations. NoseCone now offers over 40 different models or custom units - Even behind cab mounted devices.

Crosswinds

Better performance in side and crosswinds is a noted benefit of NoseCone because it maintains its high efficiency in wind angles up to 30 degrees by presenting a rounded front from all angles reducing turbulence especially on the leeward side of the truck.

Both rigids and trailers in wind tunnel tests show some cab mount devices actually increase fuel consumption due to crossflow through the deflector / pan gap.

Why Body / Pan Mounted?

While a proven, correctly installed Fuelscoop roof mounted or full aerodynamic kit provides excellent return on investment for vehicles with medium and higher annual kilometres (say, upwards of 25,000km.p.a), for older trucks and trucks travelling less than 15,000 kilometres per annum, there is no better choice than NoseCone.

They also work as a team! For higher annual kilometres, say 40,000km.p.a. when a body height exceeds the height of the highest Fuelscoop, there is proven benefit by fitting a NoseCone on the front of the body / pan to assist the performance of the Fuelscoop.

NoseCone becomes part of the body and is vibration and maintenance free. With care and minor maintenance it will last the life of the trailer or pan. At a relatively low cost you can provide an aerodynamic solution for your truck body/trailer, caravan or box trailer, no matter how old and how little it’s used.

Savings

Savings will depend on how the truck is driven. Drivers can use the increased performance to gain speed then fuel savings will be less. Driven in the same manner and speeds after fitting returns fuel savings of 10% or more.

All other NoseCone benefits still apply including better handling and increased stability especially in crosswinds.

Turbulence

NoseCone directs a smooth flow of air over the body and behind cab. Reduced turbulence means less buffeting and less cab noise. Without some positive airflow behind the cab a turbulent low pressure zone is created, increasing leeward side turbulence. Cab-pan gap causes severe turbulence particularly in cross winds Roof mounted devices increase this area of turbulence.

Increased turbulence increases the volume of the body being moved, i.e. the turbulence is drawn through the air with the body that created it. Suspended particles can remain in the turbulent slipstream along the sides and rear of the body resulting in reduced visibility for driver and other road users. NoseCone vastly reduces turbulence and minimises spray in wet weather.


Drag

NoseCone reduces drag at the rear of the pantech by reducing the volume of the box being moved. Where other deflectors assist in initial airflow over the pan roof they can create additional turbulence. This turbulence is drawn along by the body increasing its size and the vacuum behind. This void left and the air that rushes in to fill it is an additional drag.

NoseCone creates a laminar flow of air along the sides and roof of the body thereby minimising the void and easing rear drag.

Aerodynamics

An average truck uses 50% of the fuel to overcome air resistance / drag and 50% overcoming rolling resistance. Most resistance is caused by the front wall and NoseCone deals with the problem at the source.
