Prototype Development of a Snow Removal System for the SDI 218 Deicing Vehicle
(2005)Innovation
- Abstract
- The removal of snow and ice from aircraft prior to take-off is a major task at all
airports located in cold climates. Currently the removal of ice and snow is carried out
using large amounts of costly and environmentally harmful glycol that is sprayed onto
the outer surface of the aircraft. Tougher environmental regulations and a cost
conscious market have created a growing need for alternative methods that reduce
glycol consumption.
All glycol reducing systems currently available use forced air, among them Safeaero.
Customer interest has initiated a renewed push for the development of this technology
and thus the basis for this thesis.

All glycol reducing systems currently available use forced air, among them Safeaero.
Customer interest has initiated a renewed push for the development of this technology
and thus the basis for this thesis.
A prototype forced air snow removal system has been designed for use with
Safeaero’s SDI 218 deicing vehicle. The development is based on the methods
suggested by Ulrich and Eppinger [2]. Benchmarking of competitors systems and
customer interviews provided target specifications for the prototype. Research into
the characteristics of snow revealed that there is a major lack of publicly available
information on this topic. The thesis was therefore carried out based mainly the on
physical boundaries set out by the deicing vehicle. Applicable theory regarding forced
air systems were analysed, these, among others included turbo machinery, extended
Bernoulli equation and free jet velocity calculations.
Two primary factors where established that define the effectiveness of the system;
these are effective working area and effective free jet length. A series of concepts
where generated that achieved these goals in different ways. A concept was selected
which utilizes a compound nozzle that allows the adjustment of the outlet between
two fixed diameters. It is anticipated that at high velocity (closed nozzle) the jet
stream will break up the snow before the lower velocity (open nozzle) removes the
loose snow. The nozzle is attached to the deicing vehicle by a manoeuvrable duct
with a fixed bend, which allows maximum access to the aircraft while minimizing
weight.
The prototype has been taken through to production. Once assembled a large amount
of testing will be required to verify the effectiveness of the design principle. A test
plan has been developed to give a guideline for the continuation of this thesis. (Less)
