To succeed, players will need to equip and customize their soldiers to make them a well oiled, effective fighting force … eventually gaining knowledge of secrets literally beyond imagination. The goal? Establish contact with any surviving alien beings and uncover the factors that led to the extinction of their civilization. In RAM Pressure, players will engage in pitched battles against other units as well hostile intelligence services. This is only the tip of the iceberg as far as “first contact” goes: Humanity faces a much more serious threat that could lead to the total eradication of mankind. In time – while performing extremely dangerous incursions for alien artifacts – players begin to lift the veil behind government conspiracies and state-sponsored attempts to use alien technology to control the world’s population. As leaders of competing paramilitary organizations, players have to successfully scout, secure, and deliver the weapons and intel found in each alien crash site to paying governments indifferent to loss of life. To avoid widespread panic, world governments hide the truth from the population by sending elite mercenary squads to crash sites – gaining access to the alien technology before anyone else can do the same. In the near future, Earth is hit by an unusual meteorite swarm: the remains of alien fleets decimated by an ancient galactic war. Experience intense tactical online multiplayer action and explore a deep plot and unique storyline built on both single-player and multiplayer missions. As soon as the engine doesn't need to suck, and air is forced into the inlet - you have reached the ram recovery point.RAM Pressure will feature a massive selection of weapons, classes, and skills in heated gun battles across the globe. In an idle engine run on the ground, the engine has to suck in air. You reach the ram recovery point as soon as the inlet pressure (ram pressure) is greater than the ambient pressure. (From the Dale Crane part 66 Powerplant book). Here is a graph showing the result of ram recovery speed, and the point where the forces are equal. Though you could see the ram recovery point as the moment the airspeed effect on thrust and and the ram effect on thrust are equal. I had a chat about this with my turbine engine teacher, which changed my understanding on the subject. This happens because you push the air molecules together. Ram pressure increases when you fly into the air molecules fast. In class, we haven't talked about it as a specific recovery point.īut as a gradual increase in thrust based on airspeed.Īirspeed thrust decreases as the altitude increases. As density increases, and if we assume constant RPM (and thus volume) the mass of the air flowing through the engine increases.Īt some point the increased mass flow $Q$ has compensated the loss of velocity change in the engine and thrust has reached its stationary engine value. That means that the density of air in the inlet increases. The thrust ( $T$) of an engine is $T = Q(V_$ increases, the net result is that engine begins to lose thrust.īut as the speed increases past about Mach 0.2, which equals approximately 130kts at sea level at standard day conditions, the air being packed (rammed) in the engine inlet begins to compress due to increasing pressure.
