This post is about a unique artifact on display at Dryden – The Lunar Lander Research Vehicle – one of the most impressive testaments to the spirit of the 60’s space program. Not really a spiffy looking thing, the LLRV was not capable of amazing technological feats. All it was designed to do was allow future lunar lander pilots to feel what a lunar landing would feel like. Remember the computer-based flight simulators were not available back then.
So in true hard-core engineering fashion, a contraption was designed to simulate the lunar environment.
Step 1: Start with an aluminum-tube truss.
Step 2: Stick a large jet engine at its center, pointing downwards, so it tends to bouy the vehicle. If the jet engine is running at full power, the vehicle will rise to altitude. If the jet engine is then throttled back to provide a thrust equal to only 5/6 of the vehicle’s weight, then the vehicle will fall towards the ground at 1/6g – just like on the moon.
Step 3: Place the entire engine on a gimbal so it can tip and tilt so that it points exactly downwards even when the vehicle is not flying level (as the lunar gravity would act). Also use the gimbal action to compensated for forces induced by air flow, such as wind and drag, to give the pilot a true moon-like flying environment.
Step 4: Add a set of rockets that replicates the real Lunar Lander rocket systems
Step 5: Add pilot and ejection seat.
Step 6: Voila! – Fly and enjoy.
The contraption looks like a tube warehouse and is 100% function – not a single component there gives it a better look, or a stylish appearance…. it is built to simply do. I found it very refreshing. What would cars look like if they were built to simply move people (safely, comfortably) from place to place?
Three of these flying bedsteads were lost, btw, but all pilots (including Neil Armstrong) ejected safely.
The craft was built in just a bit more than a year, btw, and were the only tool Neil Armstrong had to simulate the lunar landing. This is really important to realize – when Neil Armstrong was descending onto the surface of the moon, with a fuel reserve of about a minute, he was playing real-life lunar-lander with his life, and the only previous experience he had was the flying bedstead.
Just another testament to the spirit of the Apollo program, here at Dryden.






For the obvious reasons, I invariably get too busy to blog exactly when things get interesting...
