RBS-70 Directed Study

Question 1

What is MiC?

Answer 1

Missile in Container

Question 2

The launch motor accelerates the missile to
what speed?

Answer 2

50m/s

Question 3

Wing unfolding is caused by:

Answer 3

Spring loaded wing supports pushing away from missile body
The acceleration of the missile, and
Aerodynamic forces

Question 4

Safe and Arming Device description (firing stimuli in bold)

Answer 4

Located at rear of explosive charge
Requires firing stimuli to begin arming
Wing Switch (upon missile exit of tube)
7g G Switch (in SAD)
Internal mechanical safety
Interrupter slide held out of alignment
Stepper motor moves slide from safe to arm

Question 5

Warhead payload

Answer 5

A 0.475KG OCTOL CHARGE CAST IN A STEEL CASING WITH 3000 TUNGSTEN PELLETS CAST IN A REINFORCED EPOXY PLASTIC MATRIX ON THE OUTSIDE OF THE CASING with a Shaped charge. Aluminium and Magnesium from missile body also contribute to heat.

Question 6

Proximity Fuze distances

Answer 6

Proximity Fuze
Minimum detection 0.4m
Maximum detection 6m
Typical detonation range 4m

Question 7

Prox fuze modes of operation

Answer 7

Off – utilised when engaging armoured targets, ground targets or targets close to cover
Normal – Normal delay mode utilised to engage larger targets, allows missile to detonate closer to target. Delay dependent on missile velocity
Small Target – for use against UAVs or stand-off weapons.

Question 8

Missile Storage requirements

Answer 8

The Missile in its container does not require any special storage as it is separated from the rest of firing unit until time of firing.

Storage Environment Long term storage conditions are recommended as:

Max mean temp 25°C
Max temperature 25°C
Max air humidity 60% Relative Humidity (RH)

In order to avoid corrosion damage the RBS70 equipment has been provided with air tight seals and dessicants

Missile container is filled with dehumidified air which should be replaced if container has been opened

Question 9

New developments of RBS-70

Answer 9

Bolide Missiles and the RBS 70 Freon Free (FF) Day/Night E 21 system has been purchased under the Land 19 Project.

Question 10

RB70 Testing requirements

Answer 10

Missile Test Equipment (MTE) is used for depot/workshop testing of the MiC
MTE is use for testing all missile functions except for:

 Gyro
 Accelerometer
 Launch Motor
 Sustainer Motor
 Warhead, and
 Thermal Battery

Testing needs to be carried out every 4 years

MTE is set up at Adelaide (PENFIELD) - primary storage location

Missiles should be tested in isolated area
All components and personnel are to be earthed
Pilot lamp is to be on during testing and no personnel to enter when light is on
Power is to be cut to test equipment if a fault occurs in the sustainer motor wing switch

Question 11

Missile Fuselage is divided into three section
Name the three sections:

Answer 11

Rear - Sustainer - Forward
