Did A Boeing 747 -100 Have Any New Tech?

When the first generation wide body came out, both the trijet had advance cockpit for there day. The 747 100 was referred to by many of books, as a big 707. So my question is did they put any new tech in the 747-100 when they first started service, and if so what where they.

I think your chronology is a bit off. The 747 was the first widebody. The trijets came a bit later.

As for new technology, the engines were a big leap. More powerful than anything mounted on a commercial airliner and the first major civil application of a high bypass turbofan. In fact, without those engines building a 747 was pretty much impossible.

It also had more redundancy than any other aircraft at that time, including a third wing spar.

I know the 747 was the first widebody. I just was using L-1011 and DC-10 as example. Not to get off topic but the 747 was competitor of the L1011 and DC-10. Boeing just had the gut's and Pan Am backing, to build a bigger plane.

They weren't really competitors. Apart from the significant size difference, the 747 was built for long haul, while the triplets were built for transcon/medium haul. Many operators bought the 747 for range first, capacity second, which explains why they got rid of them when the 767s came out. Later versions of the DC-10 and the L-1011 did indeed have extended range in response to customer demand. These can properly be called long haul aircraft.

You can also see it in the customer profile. Pan Am needed longer range than transcon since their route structure was more international.

Boeing did indeed have the guts, but some work on a large aircraft had been done on the Boeing bid for what later became the C-5 (which Boeing lost). The project was possible because of engine technology coming out at the time to power the C-5.

Also, there was a belief at the time that the 747 would be a pax carrier for maybe 15 years before being supplanted by SSTs. This explains the raised cockpit. DC and Lockheed may have felt that building a long haul widebody was unwise at the time. But mostly it was Pan Am actually asking for the plane. If they had asked DC, the aviation world would have been a different place today. But I digress.

I do not think there was too much difference between the Trijets and the B747 flight deck in that they were analogue gauging and 3 man crew aircraft but in that thay were different as in longhaul aircraft before them there was always a provision to carry a navigator.

So what made the navigator redundant well the inclusion of INS navigation system and the B747 was I believe the first commercial passenger aircraft to have this fitted as standard fit.

I remember that BOAC were so unsure of the reliability of INS that their first few B747 were delivered with a navigation periscope fitting in place.

I am sure it introduced many other new concepts but that is my offering

I didn't know there were any -100's built that didn't have the cigarrette smoke removal hole in the top.
By way of technology, the autopilot was a quantum leap forward in integration when compared to others of that time in the '60's; as was the flight director and air data systems. All of these systems interfaced with the result being a much smoother and snag free ride compared to just five years earlier.

Damnit. Now I have to get the book out again.  Wink

Another advance, for Boeing at least, was the automatic flight control system (AFCS), which integrated several functions. These inclided dual autopilot and flight director systems (AP/FD), a dual-channel yaw damper, and an autothrottle. Boeing called the consolidation of autopilot and flight-director circuitry "a significant innovation in the 747". The combination was achieved because much of the computer capability required for an autopilot was identical to that needed for a flight director. The autopilot function provided fully automatic attitude and heading control and manual control via flight computers or optional contro-wheel steering. The flight directors, meanwhile, displayed the required command to the pilot in most autopilot and flight director modes.

It goes on. But in short, they integrated the Autopilots and the Flight Directors.

I think most of your list is spot on, but the 727 had triple slotted TE flaps before the 747, so your question mark was appropriate.  Wink

I have that book too, lots of good info in that one.

Definitely a technical advance for it's day, then. Probably the first true "Push Button, Go Far" implementation, you just switch on the autopilot after takeoff  Wink

In addition, I believe the 747 was the first to use "composites," but this primative composite material was PVC Honeycomb Plastic with an aluminum coating. It was found on the wing fillets and the vertical stabilizer (I think).

As previously noted, the 727 and 737 used triple slotted flaps prior to the 747.

The 727 has a split rudder.

Is it fair to say, that apart from it's size, the 747 didn't pioneer much radically new technology that wasn't a logical continuation of what had been launched on previous aircraft OR would have appeared in the DC10, L1011, A300, BAC311 or whatever? The engines were a massive leap, but then that was the engine manufacturers' leap.

That's not a criticism, just a suggestion that the radical size and financial risk were probably leaps enough.

Oddly similar to another large aircraft, the 380.

Another similarity is the way the doomongers are saying the 380 will finish Airbus, the 747 nearly finished Boeing. I well remember seeing photo's of 747's lined up at Everett(?) with childs paddling pools being used as intake blanks in an effort to save money.

As I recall, they had to hang concrete weights on the pylons to avoid the wing spars distorting since the engines were late.

If I remember correctly, TWA tried the first in-flight video system, with the film circulating around the cabin, and mini-TV's (I say that jokingly, the Televisions of the early 60's were huge) spaced every 3 rows. The system had a major problem though: While the TVs each recieved the video from the very frame as it went by that row, the sound was picked up at one location only. So passengers would hear sound effects and dialog several minutes before they "saw" it.

I also forgot, the 747 was the first American airliner, if not the THE first airliner period, to have overhead bins as we know them today. Prior to that, the early jets had open racks for carry-on baggage, reminicient of the piston-era airliners.

The first Boeing to use composites was the 727. Locations of these composites were the radome, fairings and trailing edge panels.
