AF1 Redundant Flight System
The AF1 is the introductory model of vehicle control
and management system from RFDesign. The AF 1
has integrated multiple redundancy solutions
designed to provide safety and reliability in a highly
configurable package.
MINIMISING POINTS OF FAILURE.
AF1 is able to cope with most single failures and several dual
failures.
Safety & reliability assured.
2 independent and isolated CANbuses giving high noise immunity
Short and open bus redundancy – simplifying the wiring.
Any power failure is isolated; alternative power provided,
securing the system against voltage fluctuations and short
circuits.
Failure isolation and self-correcting platform.
AF3 Redundant Flight System
The AF3 will be the latest in a family of
vehicle control and and management
systems with integrated, multiple
redundancy solutions designed to
provide safety and reliability in a highly
configurable package.
NO SINGLE
POINT OF FAILURE
Designed based on a non-single point of failure
approach, the AF Series is able to cope with all single
failures and several dual and triple failures* (Depending
on the nature of the failure at hand, however, the
performance or remaining flight time may be shortened).
3 ISOLATED CAN BUSES
The AF Series presents up to three independent and
isolated CANbuses to eliminate ground loops, to
provide high noise immunity, and short & open bus
redundancy, greatly simplifying the wiring.
UP TO 3 FLIGHT CONTROLLERS &
DISTRIBUTED ARBITRATION SYSTEM
With up to three flight controllers, each with its own
independent set of sensors, a distributed arbitration
system actively chooses the best flight solution at any
given time. Due to its distributed nature, the system can
always choose and seamlessly change over among flight
solutions even when some subsystems are not
operational.
POWER PROTECTIONS
& REDUNDANCY
Any power failure is isolated and alternative power flow
provided whenever possible to ensure the system is
secure against over-voltages, under-voltages,
over-currents and short-circuits.
FAILURE ISOLATION AND
SELF-CORRECTING PLATFORM
Moreover, the system is able to identify failures such as
engine failures and actively rearrange the thrust and
surface characteristics of the remining control actuators
to provide optimal flying capabilities.
SIMPLE INTERFACE TO GROUND
CONTROL STATION
The virtual flight controller concept has been introduced
to interface the three-flight controller system to the
ground control station in such a way that to the
operator, he/she is only flying one aircraft, greatly
reducing the learning curve and minimizing the
necessary training.
Relevant flight controller status messages are sent back
via telemetry link so the operator rapidly becomes aware
of failures in any of the avionics subsystems.
MODULAR AND SCALABLE
It has been designed to be modular and scalable which
means you can adapt it to almost any platform, just by
adding or removing subsystems.
COMPATIBLE WITH NON-CAN
SUBSYSTEMS
Additionally, the system presents multiple interfaces to
control other subsystems not necessarily compatible
with CAN USART/GPIOs/PWM/I2C/CAN.
