PTRE Applications
Three uses for PTREs have been investigated: unmanned aerial vehicles (UAVs),
ramjet-assisted missiles (RAMs), and single-stage reusable vehicles (SSRVs).
UNMANNED AERIAL VEHICLE {UAV)
Figure 6 shows range versus positron mass for a 60-kg UAV with lift/drag of four that
can circumnavigate Earth on 150 µg of positrons. 14 It is modeled after the LOCASS
turbojet (Figure 7) at the Air Force Research Laboratory (AFRL), Eglin Air Force Base,
Florida .15
