Development Test & Evaluation

at Flight Test Wing

Data acquisition

• Suborbital re-entry flight path

Predict

• Simulation by M&S tools and flight simulators

Test • Flight Test of glide phase

Evaluate • Data analysis

DT&E with the aim to

evaluate the

perfomance of

Italian Air Force

aircrafts to replicate

glide re-entry phase

for training missions

A T-38 A was used as airborne simulator

with gear down and speedbrake out:

1. X-24B: 4 L/D at 200 kias, 2.5 L/D

at 300 kias (constant Mach 0.5)

2. Space Shuttle: 4 L/D (fpa 14), 2

L/D (fpa 27), dependent on the

shuttle configuration and

speedbrake deflection

3. T-38 A: 2.5 L/D, 300 kias with

gear down, descent rate up to

12000 fpm at flare

Conclusions

Aero-Space System Engineering Group represents a new

technical reference point for aero-space and space studies and

analysis in Italian Air Force

These preliminary simulations showed a very good agreement

with available technical data

Further technical studies and flight test feasibility analysis are

now on-going in order to improve ItAF sub-orbital capability
