It displays typical features of an aircraft designed to reduce its signature across the electromagnetic spectrum. The flying wing is a stealthy shape, and is suited to subsonic aircraft. It also provides the volume to house internal ordnance, which is vital because external stores ruin one's RCS (Radar Cross Section). You'll notice there are basically no right-angles, because they act like cat's-eyes to radar energy. The geometry is designed to reflect radar energy away from whence it came and we can assume there is quite a lot of RAM (Radar Absorbing Material) on the leading edges etc. The undercarriage is hidden away whilst operational and the weapons bay doors of stealth aircraft are both designed to minimise RCS and to be only opened very briefly. The air intake is on the upper surface which helps hide the front face of the engine from surface based radars. We can assume a slightly serpentine intake with more RAM as well. The exhaust is shaped and has features to reduce the infra-red signature and it looks like some bypass air is mixed with the hot exhaust. As this is a demonstrator, it won't have an operational electronics suite but typically this will include lots of passive sensors and possibly LPI (Low Probability of Intercept) radar and comms links.
